Database-provided dynamic content drives the news and e-commerce sites at the heart of the Web.

1.4.4 Graphics
With PHP, you can easily create and manipulate images using the GD extension. Example provides
a text-entry field that lets the user specify the text for a button. It takes an empty button image
file, and on it centres the text passed as the GET parameter “message”. The result is then sent
back to the browser as a PNG image.
Dynamic buttons

<?
php if (isset($_GET[‘message’]))

{
// load font and image, calculate width of text
$font = ‘times’;
$size = 12;

$im = ImageCreateFromPNG(‘button.png’);
$tsize = imagettfbbox($size,0,$font,$_GET[‘message’]); // center
$dx = abs($tsize[2]-$tsize[0]);
$dy = abs($tsize[5]-$tsize[3]);

$x = ( imagesx($im) - $dx ) / 2;
$y = ( imagesy($im) - $dy ) / 2 + $dy; // draw text
$black = ImageColorAllocate($im,0,0,0);
