I think you want something like ImageMagick. A php interface to crete/write information to images or create them.

http://www.imagemagick.org/script/index.php

http://www.imagemagick.org/script/api.php#php

Example code:

<?php
 $magick_wand=NewMagickWand();
 MagickReadImage($magick_wand,'rose.jpg');
 $drawing_wand=NewDrawingWand();
 DrawSetFont($drawing_wand,"/usr/share/fonts/bitstream-vera/Vera.ttf");
 DrawSetFontSize($drawing_wand,20);
 DrawSetGravity($drawing_wand,MW_CenterGravity);
 $pixel_wand=NewPixelWand();
 PixelSetColor($pixel_wand,"white");
 DrawSetFillColor($drawing_wand,$pixel_wand);
 if (MagickAnnotateImage($magick_wand,$drawing_wand,0,0,0,"Rose") != 0)
{
 MagickEchoImageBlob( $magick_wand );
}
 else
{
  echo MagickGetExceptionString($magick_wand);
}
?>
