  28  <H2><A NAME="4_3">4.3 Using PHP directly</A></H2>
  29  <P> It is also possible to generate images directly using the command
  30   line version of PHP. This works the same way as the normal &quot;through the
  31   browser&quot; generation with the exception that no HTTP headers will be
  32   generated. Only the binary image data.</P>
  33  <P> Please make sure that you run the command line version of PHP (cli).
  34   Using the CGI SAPI version will not work since then the HTTP headers
  35   will be generated. Note: If the CGI version is used the generation of
  36   headers may be suppressed by the '-q' option.</P>
  37  <P> You can easily check the version installed by running</P>
  38  <PRE>php --version</PRE>
  39  <P> you should then get a response with something like</P>

  41  PHP 4.3.8 (cli) (built: Aug 29 2004 22:48:10)

  45  <P> The important thing here is the</P>
  46  <PRE>(cli)</PRE>
  47  <P> marker. The JpGraph library check from what SAPI API it is invoked
  48   from and adjusts the header generation accordingly.</P>
  49  <P> If all the above requirements are met then images can be generated
  50   directly on the command line and stored in a suitable file. For example
  51   by</P>
  52  <PRE>
  53  $&gt; php myimage.php &gt; image.png
  54  </PRE>
  55  <P> Please note that the file extension on the image file must match the
  56   format in which the image is generated.</P>
