Image Upload Breaks in PHP 8.1 - No uploaded images to select in editor

[clonefunnels]

Please help! Image uploading works in PHP 7.4 but it breaks in PHP 8.1 and stops showing preview images.

It looks like the uploads are working, but there are no images in the editor to select.

Do you see anything in this code that would break it in PHP 8.1?

assetManager: {
storageType : '',
storeOnChange : true,
storeAfterUpload : true,
upload: '../images',
assets : [ ],
uploadFile: function(e) {
var files = e.dataTransfer ? e.dataTransfer.files : e.target.files;
var formData = new FormData();
for(var i in files){
formData.append('file-'+i, files[i]) //containing all the selected images from local
}
$.ajax({
url: 'upload_image.php',
type: 'POST',
data: formData,
contentType:false,
crossDomain: true,
dataType: 'json',
mimeType: "multipart/form-data",
processData:false,
success: function(result){
var myJSON = [];
$.each( result['data'], function( key, value ) {
myJSON[key] = value;
});
var images = myJSON;
editor.AssetManager.add(images);
}
});

},
},

upload_image.php

if($_FILES)
{
$resultArray = array();
foreach ( $_FILES as $file){
$fileName = $file['name'];
$tmpName = $file['tmp_name'];
$fileSize = $file['size'];
$fileType = $file['type'];
if ($file['error'] != UPLOAD_ERR_OK)
{
error_log($file['error']);
echo JSON_encode(null);
}

$uploadDir = "../images/";
$targetPath = $uploadDir. $fileName;

move_uploaded_file($tmpName, $targetPath);

         	$fp = fopen($tmpName, 'r');
         	$content = fread($fp, filesize($tmpName));
         	fclose($fp);
        	$result=array(
             		'name'=>$file['name'],
             		'type'=>'image',
             		'src'=>"../images/".$fileName."",
             		'height'=>350,
             		'width'=>250
         	); 
	// we can also add code to save images in database here.
          	array_push($resultArray,$result);
}    

$response = array( 'data' => $resultArray );
echo json_encode($response);
