How can I rotate an image?
Probably not something you will want to do a lot of in ordinary day PHP use, but if you want to rotate an image use the well-named imagerotate function.
This takes the image to rotate, the angle of rotation, and a color to fill the blank space around the rotated image with.
Here’s an example:
$original = imagecreatefrompng(“myimage.png”);
$red = imageColorAllocate($original,255,0,0);
