<a href="#adodiff">Differences between ADOdb and ADO</a><br> 139 <a href="#driverguide"><b>Database Driver Guide<br> 140 </b></a><b><a href="#changes">Change Log</a></b><br> 141 </p> 142 <h2>Introduction<a name="intro"></a></h2> 143 <p>PHP's database access functions are not standardised. This creates a need for 144 a database class library to hide the differences between the different database 145 API's (encapsulate the differences) so we can easily switch databases. PHP 4.0.5 or later 146 is now required (because we use array-based str_replace).</p> 147 <p>We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, Informix, 148 PostgreSQL, FrontBase, SQLite, Interbase (Firebird and Borland variants), Foxpro, Access, ADO, DB2, SAP DB and ODBC. 149 We have had successful reports of connecting to Progress and CacheLite via ODBC. We hope more people 150 will contribute drivers to support other databases.</p> 151 <p>PHP4 supports session variables. You can store your session information using 152 ADOdb for true portability and scalability. See adodb-session.php for more information.</p> 153 <p>Also read <a href="http://phplens.com/lens/adodb/tips_portable_sql.htm">tips_portable_sql.htm</a> 154 for tips on writing 155 portable SQL.</p> 156 <h2>Unique Features of ADOdb<a name="features"></a></h2> 157 <ul> 158 <li><b>Easy for Windows programmers</b> to adapt to because many of the conventions 159 are similar to Microsoft's ADO.</li> 160 <li>Unlike other PHP database classes which focus only on select statements, 161 <b>we provide support code to handle inserts and updates which can be adapted 162 to multiple databases quickly.</b> Methods are provided for date handling, 163 string concatenation and string quoting characters for differing databases.</li> 164 <li>A<b> metatype system </b>is built in so that we can figure out that types 165 such as CHAR, TEXT and STRING are equivalent in different databases.</li> 166 <li><b>Easy to port</b> because all the database dependant code are stored in 167 stub functions. You do not need to port the core logic of the classes.</li> 168 <li><b>Portable table and index creation</b> with the <a href="docs-datadict.htm">datadict</a> classes. 169 </li><li><b>Database performance monitoring and SQL tuning</b> with the <a href="docs-perf.htm">performance monitoring</a> classes. 170 </li><li><b>Database-backed sessions</b> with the <a href="docs-session.htm">session management</a> classes.

Make sure you customize 209 the connection settings correctly. You can debug using <i>$db->debug = true</i> as shown below:</p> 210 <pre><?php<br> include('adodb/adodb.inc.php');<br> $db = <a href="#adonewconnection">ADONewConnection</a>($dbdriver); # eg 'mysql' or 'postgres'<br> $db->debug = true;<br> $db-><a href="#connect">Connect</a>($server, $user, $password, $database);<br> $rs = $db-><a href="#execute">Execute</a>('select * from some_small_table');<br> print "<pre>";<br> print_r($rs-><a href="#getrows">GetRows</a>());<br> print "</pre>";<br>?></pre> 211 212 <h3>Minimum Install<a name="mininstall"></a></h3> 213 <p>For developers who want to release a minimal install of ADOdb, you will need: 214 </p><ul> 215 <li>adodb.inc.php 216 </li><li>adodb-lib.inc.php 217 </li><li>adodb-time.inc.php 218 </li><li>drivers/adodb-$database.inc.php 219 </li><li>license.txt (for legal reasons) 220 </li><li>adodb-php4.inc.php 221 </li><li>adodb-iterator.inc.php (php5 functionality) 222 </li></ul> 223 Optional: 224 <ul> 225 <li>adodb-error.inc.php and lang/adodb-$lang.inc.php (if you use MetaError()) 226 </li><li>adodb-csvlib.inc.php (if you use cached recordsets - CacheExecute(), etc) 227 </li><li>adodb-exceptions.inc.php and adodb-errorhandler.inc.php (if you use adodb error handler or php5 exceptions). 228 <li>adodb-active-record.inc.php if you use <a href=docs-active-record.htm>Active Records</a>. 229 </li></ul> 230 231 <h3>Code Initialization Examples<a name="coding"></a></h3> 232 <p>When running ADOdb, at least two files are loaded. First is adodb/adodb.inc.php, 233 which contains all functions used by all database classes. The code specific 234 to a particular database is in the adodb/driver/adodb-????.inc.php file.</p> 235 <a name="adonewconnection"></a> 236 <p>For example, to connect to a mysql database:</p> 237 <pre>include('/path/to/set/here/adodb.inc.php');<br>$conn = &ADONewConnection('mysql');<br></pre> 238 <p>Whenever you need to connect to a database, you create a Connection object 239 using the <b>ADONewConnection</b>($driver) function. 240 <b>NewADOConnection</b>($driver) is an alternative name for the same function.</p> 241 242 <p>At this point, you are not connected to the database (no longer true if you pass in a <a href="#dsnsupport">dsn</a>). You will first need to decide 243 whether to use <i>persistent</i> or <i>non-persistent</i> connections. The advantage of <i>persistent</i> 244 connections is that they are faster, as the database connection is never closed (even 245 when you call Close()). <i>Non-persistent </i>connections take up much fewer resources though, 246 reducing the risk of your database and your web-server becoming overloaded. 247 </p><p>For persistent connections, 248 use $conn-><a href="#pconnect">PConnect()</a>, 249 or $conn-><a href="#connect">Connect()</a> for non-persistent connections. 250 Some database drivers also support <a href="#nconnect">NConnect()</a>, which forces 251 the creation of a new connection. 252 253 <a name="connection_gotcha"></a> 254 </p><p><b>Connection Gotcha</b>: If you create two connections, but both use the same userid and password, 255 PHP will share the same connection. This can cause problems if the connections are meant to 256 different databases. The solution is to always use different userid's for different databases, 257 or use NConnect(). 258 259 <a name="dsnsupport"></a> 260 </p><h3>Data Source Name (DSN) Support</h3> 261 <p> Since ADOdb 4.51, you can connect to a database by passing a dsn to NewADOConnection() (or ADONewConnection, which is 262 the same function). The dsn format is: 263 </p><pre> $driver://$username:$password@hostname/$database?options[=value]<br></pre><p> 264 NewADOConnection() calls Connect() or PConnect() internally for you. If the connection fails, false is returned. 265 </p><pre> <font color="#008000"># non-persistent connection</font> 266 $dsn = 'mysql://root:pwd@localhost/mydb'; 267 $db = NewADOConnection($dsn); 268 if (!$db) die("Connection failed"); 269 270 <font color="#008000"># no need to call connect/pconnect!</font> 271 $arr = $db->GetArray("select * from table"); 272 273 <font color="#008000"># persistent connection</font> 274 $dsn2 = 'mysql://root:pwd@localhost/mydb?persist'; 275 </pre> 276 <p> 277 If you have special characters such as /:?_ in your dsn, then you need to rawurlencode them first: 278 </p><pre> $pwd = rawurlencode($pwd);<br> $dsn = "mysql://root:$pwd@localhost/mydb"; 279 $dsn2=rawurlencode("sybase_ase")."://user:pass@host/path?query";<br></pre> 280 <p> 281 Legal options are: 282 </p><p> 283 <table align="center" border="1"><tbody><tr><td>For all drivers</td><td> 284 'persist', 'persistent', 'debug', 'fetchmode', 'new' 285 </td></tr><tr><td>Interbase/Firebird 286 </td><td> 287 'dialect','charset','buffers','role' 288 </td></tr><tr><td>M'soft ADO</td><td> 289 'charpage' 290 291 </td></tr><tr><td>MySQL</td><td> 292 'clientflags' 293 </td></tr><tr><td>MySQLi</td><td> 294 'port', 'socket', 'clientflags' 295 </td></tr><tr><td>Oci8</td><td> 296 'nls_date_format','charset' 297 </td></tr></tbody></table> 298 </p><p> 299 For all drivers, when the options <i>persist</i> or <i>persistent</i> are set, a persistent connection is forced; similarly, when <i>new</i> is set, then 300 a new connection will be created using NConnect if the underlying driver supports it. 301 The <i>debug</i> option enables debugging.

This is because it is designed in a layered fashion, 472 like an onion, with the fastest functions in the innermost layer. Stick to the 473 following functions for best performance:</p> 474 <table align="center" border="1" width="40%"> 475 <tbody><tr> 476 <td><div align="center"><b>Innermost Layer</b></div></td> 477 </tr> 478 <tr> 479 <td><p align="center">Connect, PConnect, NConnect<br> 480 Execute, CacheExecute<br> 481 SelectLimit, CacheSelectLimit<br> 482 MoveNext, Close <br> 483 qstr, Affected_Rows, Insert_ID</p></td> 484 </tr> 485 </tbody></table> 486 <p>The fastest way to access the field data is by accessing the array $recordset->fields 487 directly. Also set the global variables <a href="#adodb_fetch_mode">$ADODB_FETCH_MODE</a> 488 = ADODB_FETCH_NUM, and (for oci8, ibase/firebird and odbc) <a href="#adodb_countrecs">$ADODB_COUNTRECS</a> = false 489 before you connect to your database.</p> 490 <p>Consider using bind parameters if your database supports it, as it improves 491 query plan reuse. Use ADOdb's performance tuning system to identify bottlenecks 492 quickly. At the time of writing (Dec 2003), this means oci8 and odbc drivers.</p> 493 <p>Lastly make sure you have a PHP accelerator cache installed such as APC, Turck 494 MMCache, Zend Accelerator or ionCube.</p> 495 <p>Some examples:</p> 496 <table align="center" border="1"><tbody><tr><td><b>Fastest data retrieval using PHP</b></td><td><b>Fastest data retrieval using ADOdb extension</b></td></tr> 497 <tr><td> 498 <pre>$rs =& $rs->Execute($sql);<br>while (!$rs->EOF) {<br> var_dump($rs->fields);<br> $rs->MoveNext();<br>}</pre></td><td> 499 <pre>$rs =& $rs->Execute($sql);<br>$array = adodb_getall($rs);<br>var_dump($array);<br><br><br></pre></td></tr></tbody></table> 500 <p><b>Advanced Tips</b> 501 </p><p>If you have the <a href="http://adodb.sourceforge.net/#extension">ADOdb C extension</a> installed, 502 you can replace your calls to $rs->MoveNext() with adodb_movenext($rs). 503 This doubles the speed of this operation. For retrieving entire recordsets at once, 504 use GetArray(), which uses the high speed extension function adodb_getall($rs) internally. 505 </p><p>Execute() is the default way to run queries. You can use the low-level functions _Execute() and _query() 506 to reduce query overhead. Both these functions share the same parameters as Execute(). 507 </p><p>If you do not have any bind parameters or your database supports 508 binding (without emulation), 509 then you can call _Execute() directly. Calling this function bypasses 510 bind emulation. Debugging is still supported in _Execute(). 511 </p><p>If you do not require debugging facilities nor emulated 512 binding, and do not require a recordset to be returned, then you can 513 call _query. This is great for inserts, updates and deletes. Calling 514 this function 515 bypasses emulated binding, debugging, and recordset handling. Either 516 the resultid, true or false are returned by _query(). </p><p>For Informix, you can disable scrollable cursors with $db->cursorType = 0. 517 </p><p><a name="hack"></a> </p> 518 <h2>Hacking ADOdb Safely</h2> 519 <p>You might want to modify ADOdb for your own purposes. Luckily you can 520 still maintain backward compatibility by sub-classing ADOdb and using the $ADODB_NEWCONNECTION 521 variable. $ADODB_NEWCONNECTION allows you to override the behaviour of ADONewConnection(). 522 ADOConnection() checks for this variable and will call 523 the function-name stored in this variable if it is defined. 524 </p><p>In the following example, new functionality for the connection object 525 is placed in the <i>hack_mysql</i> and <i>hack_postgres7</i> classes. The recordset class naming convention 526 can be controlled using $rsPrefix. Here we set it to 'hack_rs_', which will make ADOdb use 527 <i>hack_rs_mysql</i> and <i>hack_rs_postgres7</i> as the recordset classes. 528 529 530 </p><pre>class hack_mysql extends adodb_mysql {<br>var $rsPrefix = 'hack_rs_';<br> /* Your mods here */<br>}<br><br>class hack_rs_mysql extends ADORecordSet_mysql {<br> /* Your mods here */<br>}<br><br>class hack_postgres7 extends adodb_postgres7 {<br>var $rsPrefix = 'hack_rs_';<br> /* Your mods here */<br>}<br><br>class hack_rs_postgres7 extends ADORecordSet_postgres7 {<br> /* Your mods here */<br>}<br><br>$ADODB_NEWCONNECTION = 'hack_factory';<br><br>function& hack_factory($driver)<br>{<br> if ($driver !== 'mysql' && $driver !== 'postgres7') return false;<br> <br> $driver = 'hack_'.$driver;<br> $obj = new $driver();<br> return $obj;<br>}<br><br>include_once ('adodb.inc.php');<br></pre> 531 <p></p><p>Don't forget to call the constructor of the parent class in 532 your constructor. If you want to use the default ADOdb drivers return 533 false in the above hack_factory() function. 534 Also you can define your own ADORecordSet_empty() class, by defining a class $$this->rsPrefix.'empty' since 4.96/5.02. 535 <a name="php5"></a> 536 </p><h2>PHP5 Features</h2> 537 ADOdb 4.02 or later will transparently determine which version of PHP you are using. 538 If PHP5 is detected, the following features become available: 539 <ul> 540 541 <li><b>PDO</b>: PDO drivers are available.

The 1235 first one is in the <b>adodb-errorhandler.inc.php</b> file. This makes use of 1236 the standard PHP functions <a href="http://php.net/error_reporting">error_reporting</a> 1237 to control what error messages types to display, and <a href="http://php.net/trigger_error">trigger_error</a> 1238 which invokes the default PHP error handler. 1239 </p><p> Including the above file will cause <i>trigger_error($errorstring,E_USER_ERROR)</i> 1240 to be called when<br> 1241 (a) Connect() or PConnect() fails, or <br> 1242 (b) a function that executes SQL statements such as Execute() or SelectLimit() 1243 has an error.<br> 1244 (c) GenID() appears to go into an infinite loop. 1245 </p><p> The $errorstring is generated by ADOdb and will contain useful debugging information 1246 similar to the error.log data generated below.

Subsequent calls to that query will used the cached version stored 1352 in $ADODB_CACHE_DIR. To force a query to execute and flush the cache, call CacheExecute() 1353 with the first parameter set to zero. Alternatively, use the CacheFlush($sql) 1354 call. </font></p> 1355 <p><font>For the sake of security, we recommend you set <i>register_globals=off</i> 1356 in php.ini if you are using $ADODB_CACHE_DIR.</font></p> 1357 <p>In ADOdb 1.80 onwards, the secs2cache parameter is optional in CacheSelectLimit() 1358 and CacheExecute().

This is implemented in Oracle, 1665 MySQL, PgSQL, MSSQL, ODBC currently. 1666 </p><p>Since ADOdb 3.11, you can force non-persistent 1667 connections even if PConnect is called by defining the constant 1668 ADODB_NEVER_PERSIST before you call PConnect. 1669 </p><p> 1670 Since 4.23, null is returned if the extension is not loaded. 1671 </p><p><b>NConnect<a name="nconnect"></a>($host,[$user],[$password],[$database])</b></p> 1672 <p>Always force a new connection. In contrast, PHP sometimes reuses connections 1673 when you use Connect() or PConnect(). Currently works only on mysql (PHP 4.3.0 1674 or later), postgresql and oci8-derived drivers.

The Parameter( 2285 ) function is the recommended way to go with bind variables.</font></p> 2286 <p><font>Bind( ) allows you to use bind variables in your sql 2287 statement. This binds a PHP variable to a name defined in an Oracle sql statement 2288 that was previously prepared using Prepare(). Oracle named variables begin with 2289 a colon, and ADOdb requires the named variables be called :0, :1, :2, :3, etc. 2290 The first invocation of Bind() will match :0, the second invocation will match 2291 :1, etc. Binding can provide 100% speedups for insert, select and update statements. 2292 </font></p> 2293 <p>The other variables, $size sets the buffer size for data storage, $type is 2294 the optional descriptor type OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File), 2295 OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID). 2296 Lastly, instead of using the default :0, :1, etc names, you can define your 2297 own bind-name using $name. 2298 </p><p><font>The following example shows 3 bind variables being used: 2299 p1, p2 and p3. These variables are bound to :0, :1 and :2.</font></p> 2300 <pre>$stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:0, :1, :2)");<br>$DB->Bind($stmt, $p1);<br>$DB->Bind($stmt, $p2);<br>$DB->Bind($stmt, $p3);<br>for ($i = 0; $i < $max; $i++) { <br> $p1 = ?; $p2 = ?; $p3 = ?;<br> $DB->Execute($stmt);<br>}</pre> 2301 <p>You can also use named variables:</p> 2302 <pre>$stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:name0, :name1, :name2)");<br>$DB->Bind($stmt, $p1, "name0");<br>$DB->Bind($stmt, $p2, "name1");<br>$DB->Bind($stmt, $p3, "name2");<br>for ($i = 0; $i < $max; $i++) { <br> $p1 = ?; $p2 = ?; $p3 = ?;<br> $DB->Execute($stmt);<br>}</pre> 2303 <p><b>LogSQL($enable=true)<a name="logsql"></a></b></p> 2304 Call this method to install a SQL logging and timing function (using fnExecute). 2305 Then all SQL statements are logged into an adodb_logsql table in a database.

If you are passing in a prepared statement, 2386 then $sql is an array (see <a href="#prepare">Prepare</a>). The fnCacheExecute 2387 function is only called if the recordset returned was cached.<font> 2388 The function parameters match the Execute and CacheExecute functions respectively, 2389 except that $this (the connection object) is passed as the first parameter.</font></p> 2390 <p>Since ADOdb 3.91, the behaviour of fnExecute varies depending on whether the 2391 defined function returns a value. If it does not return a value, then the $sql 2392 is executed as before. This is useful for query rewriting or counting sql queries. 2393 </p><p> On the other hand, you might want to replace the Execute function with one 2394 of your own design. If this is the case, then have your function return a value. 2395 If a value is returned, that value is returned immediately, without any further 2396 processing.

To ensure there is no duplication of work, kindly email me 2857 at jlim#natsoft.com.my if you decide to create such a class.</font></p> 2858 <p><font>First decide on a name in lower case to call the database 2859 type. Let's say we call it xbase. </font></p> 2860 <p><font>Then we need to create two classes ADODB_xbase and ADORecordSet_xbase 2861 in the file adodb-xbase.inc.php.</font></p> 2862 <p><font>The simplest form of database driver is an adaptation 2863 of an existing ODBC driver. Then we just need to create the class <i>ADODB_xbase 2864 extends ADODB_odbc</i> to support the new <b>date</b> and <b>timestamp</b> formats, 2865 the <b>concatenation</b> operator used, <b>true</b> and <b>false</b>. For 2866 the<i> ADORecordSet_xbase extends ADORecordSet_odbc </i>we need to change 2867 the <b>MetaType</b> function. See<b> adodb-vfp.inc.php</b> as an example.</font></p> 2868 <p><font>More complicated is a totally new database driver that 2869 connects to a new PHP extension. Then you will need to implement several 2870 functions. Fortunately, you do not have to modify most of the complex code. 2871 You only need to override a few stub functions. See <b>adodb-mysql.inc.php</b> for 2872 example.</font></p> 2873 <p><font>The default date format of ADOdb internally is YYYY-MM-DD 2874 (Ansi-92).
