Transparent Circular Crop

<?php
    $upload_dir = 'upload-image/';
    $uploaded_file = $upload_dir . 'example.jpg';

    $image_s = imagecreatefromstring(file_get_contents($uploaded_file));
    $width = imagesx($image_s);
    $height = imagesy($image_s);

    $newwidth = 460;
    $newheight = 480;

    $image = imagecreatetruecolor($newwidth, $newheight);
    imagealphablending($image, true);
    imagecopyresampled($image, $image_s, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

    //create masking
    $mask = imagecreatetruecolor($newwidth, $newheight);

    $transparent = imagecolorallocate($mask, 255, 0, 0);
    imagecolortransparent($mask,$transparent);
    imagefilledellipse($mask, $newwidth/2, $newheight/2, $newwidth, $newheight, $transparent);

    $red = imagecolorallocate($mask, 0, 0, 0);
    imagecopymerge($image, $mask, 0, 0, 0, 0, $newwidth, $newheight, 100);
    imagecolortransparent($image,$red);
    imagefill($image, 0, 0, $red);

    //output, save and free memory
    header('Content-type: image/png');
    // Save the rounded image
    $rounded_file = $upload_dir . 'rounded_example.png';
    imagepng($image, $rounded_file);

    // Free up memory
    imagedestroy($image);
    imagedestroy($mask);

    // Optionally, you can delete the uploaded file if you no longer need it
    // @unlink($uploaded_file);
