Alteration to kmrohe's function, so it rotates both 90 degrees CW and CCW.
<?php
function KmroheRotate($image, $rotation) {
$width = imagesx($image);
$height = imagesy($image);
$newimage = imagecreatetruecolor($height, $width);
imagealphablending($newimage, false);
imagesavealpha($newimage, true);
for ( $w=0; $w<$width; $w++)
for ( $h = 0 ; $h<$height ; $h++) {
$reference = imagecolorat($image, $w, $h);
if ( $rotation == "90" ) {
imagesetpixel($newimage, $h, ($width - 1) - $w, $reference);
} else {
imagesetpixel($newimage, ($height - 1) - $h, $w, $reference);
}
}
return $newimage;
}
?>
