Are there any best practices for validating image dimensions in PHP before processing them further?

When working with images in PHP, it's important to validate their dimensions before processing them further to prevent potential issues such as memory exhaustion or distorted images. One way to validate image dimensions is by using the getimagesize() function in PHP, which returns an array containing the image width and height. 

// Validate image dimensions before processing further
$image_path = 'path/to/image.jpg';
$dimensions = getimagesize($image_path);

if ($dimensions === false) {
    // Handle error, invalid image file
} else {
    $width = $dimensions[0];
    $height = $dimensions[1];

    // Further processing logic here
}
