Rotate an image with a given angle
(PHP 4 >= 4.3.0, PHP 5)
resource imagerotate ( resource source_image, float angle, int bgd_color [, int ignore_transparent] )
Rotates the source_image image using the given angle in degrees.
The center of rotation is the center of the image, and the rotated image is scaled down so that the whole rotated image fits in the destination image - the edges are not clipped.

- ignore_transparent
If set and non-zero, transparent colors are ignored (otherwise kept).

<?php
// File and rotation
$filename = 'test.jpg';
$degrees = 180;
// Content type
header('Content-type: image/jpeg');
// Load
$source = imagecreatefromjpeg($filename);
// Rotate
$rotate = imagerotate($source, $degrees, 0);
// Output
imagejpeg($rotate);
?>The above example will output something similar to:
