<?php
function mergeImageLayers($layerMethodType, $imagePath1, $imagePath2) {

    $imagick = new \Imagick(realpath($imagePath));

    $imagick2 = new \Imagick(realpath($imagePath2));
    $imagick->addImage($imagick2);
    $imagick->setImageFormat('png');

    $result = $imagick->mergeImageLayers($layerMethodType);
    header("Content-Type: image/png");
    echo $result->getImageBlob();
}
