Is there a way to create graphs such as pie charts or bar charts etc in php?

Yes, imagefilledarc and imagefilledrectangle will do the trick...

thanks .

Yup, if you want some examples look for some web statistic softwarepackages, it's often used in that. Also on www.planetsourcecode.com you can find alot of nice examples of all sorts of charts and graphs in php.

Fatal error: Call to undefined function: imagecreatetruecolor() in

using the test code:

<?php

// create image
$image = imagecreatetruecolor(100, 100);

// allocate some solors
$white    = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
$gray    = imagecolorallocate($image, 0xC0, 0xC0, 0xC0);
$darkgray = imagecolorallocate($image, 0x90, 0x90, 0x90);

$darknavy = imagecolorallocate($image, 0x00, 0x00, 0x50);

// flush image

imagepng($image);
imagedestroy($image);

Do you have the GD library installed?

php must be configured to find the extensions that hold the graphical functions.
eg: php_gd2.dll
