What are some functions in PHP that can be used to crop images?

When working with images in PHP, you may need to crop them to a specific size or aspect ratio. To achieve this, you can use functions such as `imagecrop()` or `imagecopyresampled()`. These functions allow you to specify the coordinates and dimensions of the area you want to crop from the original image. 

// Example of cropping an image using imagecopyresampled()

// Load the original image
$original_image = imagecreatefromjpeg('original.jpg');

// Define the coordinates and dimensions of the area to crop
$crop_x = 0;
$crop_y = 0;
$crop_width = 200;
$crop_height = 200;

// Create a new image with the cropped area
$cropped_image = imagecreatetruecolor($crop_width, $crop_height);
imagecopyresampled($cropped_image, $original_image, 0, 0, $crop_x, $crop_y, $crop_width, $crop_height, $crop_width, $crop_height);

// Save the cropped image
imagejpeg($cropped_image, 'cropped.jpg');

// Free up memory
imagedestroy($original_image);
imagedestroy($cropped_image);
