Re: Storing binary data within a php script.

[Jed Smith <jed@xxxxxx>]

This is done in a few examples using base64_encode() and base64_decode(). A particular OpenGL 
example I can recall encoded a small (~20k) DLL directly into the PHP source that relied upon it, 
then unpacked it at runtime.

Ah, there it is:

   ** snip **

  if ( is_file( "SimpleWndProc.dll" ) ? filesize( "SimpleWndProc.dll" ) != 2560 : 1 )
  {
     $dll = "eNrtVU9IFGEUf7NpTbZue1hCYqlvQT3JslsG0clt/aho1XHNDOnguDutY+uMzh80"
          . "KDrYQTPJS1TUoWMEdSpYrEOEsQl66yD9gT1ILCHhIcqDML35Zla3IgO7mQ9+733v"
	  /* ... */
          . "dxBP8K4dRTzGcY6dBwcd8sBgVupS0lgfi9siXnQPAErZOyqrYXMXwO/8l7oiy5Fv"
          . "kdWIJ8pHfdFAdH90uzf+D/QDFVAQCA==";

    $dllout = fopen( "SimpleWndProc.dll", "wb" );

    if ( !$dllout )
      die( "Unable to extract SimpleWndProc.dll" );

    fwrite( $dllout, gzuncompress( base64_decode( $dll ) ) );
    fclose( $dllout );

  ---------------

That's from an iridium example. You just base64 encode the data and enclose it in a string. Of 
course, that's simply one way of doing it.
