| utf8_encodeFN($file,$safe=true) X-Ref |
| URL-Encode a filename to allow unicodecharacters Slashes are not encoded When the second parameter is true the string will be encoded only if non ASCII characters are detected - This makes it safe to run it multiple times on the same string (default is true) author: Andreas Gohr <andi@splitbrain.org> |
| utf8_decodeFN($file) X-Ref |
| URL-Decode a filename This is just a wrapper around urldecode author: Andreas Gohr <andi@splitbrain.org> |
| utf8_isASCII($str) X-Ref |
| Checks if a string contains 7bit ASCII only author: Andreas Gohr <andi@splitbrain.org> |
| utf8_strip($str) X-Ref |
| Strips all highbyte chars Returns a pure ASCII7 string author: Andreas Gohr <andi@splitbrain.org> |
| utf8_check($Str) X-Ref |
| Tries to detect if a string is in Unicode encoding author: <bmorel@ssi.fr> |
| utf8_strlen($string) X-Ref |
| Unicode aware replacement for strlen() utf8_decode() converts characters that are not in ISO-8859-1 to '?', which, for the purpose of counting, is alright - It's even faster than mb_strlen. author: <chernyshevsky at hotmail dot com> |
| utf8_substr($str, $offset, $length = null) X-Ref |
| UTF-8 aware alternative to substr Return part of a string given character offset (and optionally length) author: Harry Fuecks <hfuecks@gmail.com> author: Chris Smith <chris@jalakai.co.uk> param: string param: integer number of UTF-8 characters offset (from left) param: integer (optional) length in UTF-8 characters from offset return: mixed string or FALSE if failure |
| utf8_substr_replace($string, $replacement, $start , $length=0 ) X-Ref |
| Unicode aware replacement for substr_replace() author: Andreas Gohr <andi@splitbrain.org> |
| utf8_explode($sep, $str) X-Ref |
| Unicode aware replacement for explode author: Harry Fuecks <hfuecks@gmail.com> |
| utf8_str_replace($s,$r,$str) X-Ref |
| Unicode aware replacement for strrepalce() author: Harry Fuecks <hfuecks@gmail.com> |
| utf8_ltrim($str,$charlist='') X-Ref |
| Unicode aware replacement for ltrim() author: Andreas Gohr <andi@splitbrain.org> return: string |
| utf8_rtrim($str,$charlist='') X-Ref |
| Unicode aware replacement for rtrim() author: Andreas Gohr <andi@splitbrain.org> return: string |
| utf8_trim($str,$charlist='') X-Ref |
| Unicode aware replacement for trim() author: Andreas Gohr <andi@splitbrain.org> return: string |
| utf8_strtolower($string) X-Ref |
| This is a unicode aware replacement for strtolower() Uses mb_string extension if available author: Andreas Gohr <andi@splitbrain.org> |
| utf8_strtoupper($string) X-Ref |
| This is a unicode aware replacement for strtoupper() Uses mb_string extension if available author: Andreas Gohr <andi@splitbrain.org> |
| utf8_deaccent($string,$case=0) X-Ref |
| Replace accented UTF-8 characters by unaccented ASCII-7 equivalents Use the optional parameter to just deaccent lower ($case = -1) or upper ($case = 1) letters. Default is to deaccent both cases ($case = 0) author: Andreas Gohr <andi@splitbrain.org> |
| utf8_romanize($string) X-Ref |
| Romanize a non-latin string author: Andreas Gohr <andi@splitbrain.org> |
| utf8_stripspecials($string,$repl='',$additional='') X-Ref |
| Removes special characters (nonalphanumeric) from a UTF-8 string This function adds the controlchars 0x00 to 0x19 to the array of stripped chars (they are not included in $UTF8_SPECIAL_CHARS) author: Andreas Gohr <andi@splitbrain.org> param: string $string The UTF8 string to strip of special chars param: string $repl Replace special with this string param: string $additional Additional chars to strip (used in regexp char class) |
| utf8_strpos($haystack, $needle,$offset=0) X-Ref |
| This is an Unicode aware replacement for strpos Uses mb_string extension if available author: Harry Fuecks <hfuecks@gmail.com> |
| utf8_tohtml($str) X-Ref |
| Encodes UTF-8 characters to HTML entities author: <vpribish at shopping dot com> |
| utf8_to_unicode($str,$strict=false) X-Ref |
| Takes an UTF-8 string and returns an array of ints representing the Unicode characters. Astral planes are supported ie. the ints in the output can be > 0xFFFF. Occurrances of the BOM are ignored. Surrogates are not allowed. If $strict is set to true the function returns false if the input string isn't a valid UTF-8 octet sequence and raises a PHP error at level E_USER_WARNING Note: this function has been modified slightly in this library to trigger errors on encountering bad bytes author: <hsivonen@iki.fi> author: Harry Fuecks <hfuecks@gmail.com> param: string UTF-8 encoded string param: boolean Check for invalid sequences? return: mixed array of unicode code points or FALSE if UTF-8 invalid |
| unicode_to_utf8($arr,$strict=false) X-Ref |
| Takes an array of ints representing the Unicode characters and returns a UTF-8 string. Astral planes are supported ie. the ints in the input can be > 0xFFFF. Occurrances of the BOM are ignored. Surrogates are not allowed. If $strict is set to true the function returns false if the input array contains ints that represent surrogates or are outside the Unicode range and raises a PHP error at level E_USER_WARNING Note: this function has been modified slightly in this library to use output buffering to concatenate the UTF-8 string (faster) as well as reference the array by it's keys author: <hsivonen@iki.fi> author: Harry Fuecks <hfuecks@gmail.com> param: array of unicode code points representing a string param: boolean Check for invalid sequences? return: mixed UTF-8 string or FALSE if array contains invalid code points |
| utf8_to_utf16be(&$str, $bom = false) X-Ref |
| UTF-8 to UTF-16BE conversion. Maybe really UCS-2 without mb_string due to utf8_to_unicode limits |
| utf16be_to_utf8(&$str) X-Ref |
| UTF-8 to UTF-16BE conversion. Maybe really UCS-2 without mb_string due to utf8_to_unicode limits |
| utf8_bad_replace($str, $replace = '') X-Ref |
| Replace bad bytes with an alternative character ASCII character is recommended for replacement char PCRE Pattern to locate bad bytes in a UTF-8 string Comes from W3 FAQ: Multilingual Forms Note: modified to include full ASCII range including control chars author: Harry Fuecks <hfuecks@gmail.com> param: string to search param: string to replace bad bytes with (defaults to '?') - use ASCII return: string |
| utf8_correctIdx(&$str,$i,$next=false) X-Ref |
| adjust a byte index into a utf8 string to a utf8 character boundary author: chris smith <chris@jalakai.co.uk> param: $str string utf8 character string param: $i int byte index into $str param: $next bool direction to search for boundary, return: int byte index into $str now pointing to a utf8 character boundary |
