Is there a more efficient way to resize and process images in PHP to prevent memory limit errors during execution?

When resizing and processing images in PHP, memory limit errors can occur when dealing with large images. To prevent these errors, you can use the `imagecreatefromjpeg`, `imagecreatefrompng`, or `imagecreatefromgif` functions to create a resized version of the image without loading the entire image into memory. This allows you to work with the image in smaller chunks, reducing memory usage. 

function resizeImage($source, $destination, $newWidth, $newHeight) {
    list($width, $height) = getimagesize($source);
    $image = imagecreatetruecolor($newWidth, $newHeight);
    
    $sourceImage = imagecreatefromjpeg($source); // Change function based on image type
    
    imagecopyresampled($image, $sourceImage, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
    
    imagejpeg($image, $destination); // Change function based on desired output format
    
    imagedestroy($image);
    imagedestroy($sourceImage);
}

// Example usage
resizeImage('input.jpg', 'output.jpg', 200, 200);
