Crop image in PHP.

I was looking for a simple way to crop part of an image using PHP code. The idea of this is to create image thumbnail for large images uploaded. These large images could be used for previews, screen shots, wallpapers.. etc.
And because we don’t have an exact ratio between Image width and height, we should crop part of the original image to use it as a thumbnail.
Note: we can find the ratio between width and height and then resize the image. But this won’t work prefect, so we better use cropping to get the size we need.
Also, we can crop part of resized image to use it as a thumbnail.
Let me now explain the code used to crop part of image.
// Receiving image.
$image = $_FILES["image"]["tmp_name"];
// Creating temp image as a source image (original image).
$src = imagecreatefromjpeg($image);
// Create new image with a new width and height.
$dest = imagecreatetruecolor($width, $height);
// Copy new image to memory after cropping.
imagecopy($dest, $src, 0, 0, $left, $top, $width, $height);
$compress = 60;
// Creating new image cropped image as JPG and save it to $dest
// Freeing up memory.
Hope this will be helpful.
