Hit PHP from node server to process images - php

Question

I'm trying to hit a php page from a node server so that it will generate some thumbnail images. The problem is that it isn't generating the images when i hit do a jquery.get request from node. It works perfectly if I hit the page from a browser, though.
Here is the php code:
<?php
$thumbsFolder = 'output/thumbs/';
$mediumFolder = 'output/medium/';
$originals = glob("output/*.jpg");
$thumbs = glob("output/thumbs/*.jpg");
// only process the images that are missing
$diff = array_diff($originals, $thumbs);
foreach ($diff as $file) {
processImage($file, $thumbsFolder, 150);
processImage($file, $mediumFolder, 600);
}
function processImage($imagePath, $outputFolder, $targetWidth){
$imageSize = getimagesize($imagePath);
$originalWidth = $imageSize[0];
$originalHeight = $imageSize[1];
$targetHeight = round($originalHeight * $targetWidth / $originalWidth);
$urlElements = explode("/", $imagePath);
$fileName = array_pop($urlElements);
$fileName = explode(".", $fileName);
$ext = array_pop($fileName);
$newFilePath = $outputFolder.join($fileName, "").".".$ext;
$im = imagecreatefromjpeg($imagePath);
$sm = imagecreatetruecolor($targetWidth, $targetHeight);
imagealphablending($sm, false);
imagecopyresampled($sm, $im, 0, 0, 0, 0, $targetWidth, $targetHeight, $originalWidth, $originalHeight);
imagejpeg($sm, $newFilePath, 75);
}
?>
Here is the node script that hits the endpoint.
$.get("http://absolutepath.com/pi-lapse/thumb-gen.php", function(e){console.log(e)})
I also tried curl, and it didn't work.
