Responsive File Manager upload issues - php

Question

I've been running the Responsive File Manager recently, both on my local machine as well as a hosted server and have received different issues for each, despite the code being the same. These issues are all related to the uploading of files - currently the tested files have all been only JPEG files, where JPEG files larger than 2 MB are not able to be uploaded.
Shared issues:
For both local machine & hosted server, if the uploaded image exceeds 8MB, then I receive the following error message:
The uploaded file exceeds the max size allowed
Local machine issues:
For the local machine only, if the uploaded image is greater than 2MB but less than 8MB, I receive the following error message:
Warning: mime_content_type(): Empty filename or path in C:\xampp\htdocs\project\webroot\3rdparty\responsive file manager\filemanager\upload.php on line 92
where line 92 refers to this specific line within a set of if statements:
if ( ! empty($_FILES) || isset($_POST['url']))
{
if(isset($_POST['url'])){
$temp = tempnam('/tmp','RF');
$handle = fopen($temp, "w");
fwrite($handle, file_get_contents($_POST['url']));
fclose($handle);
$_FILES['file']= array(
'name' => basename($_POST['url']),
'tmp_name' => $temp,
'size' => filesize($temp),
'type' => explode(".", strtolower($temp))
);
}
$info = pathinfo($_FILES['file']['name']);
$mime_type = $_FILES['file']['type'];
if (function_exists('mime_content_type')){
$mime_type = mime_content_type($_FILES['file']['tmp_name']); //line 92
}
}
I also receive this error as well:
File extension is not allowed. (#C:\xampp\htdocs\project\webroot\3rdparty\responsive file manager\filemanager\upload.php#260)
which refers to this set of if statements:
if ( ! empty($_FILES) || isset($_POST['url']))
{
else // file ext. is not in the allowed list
{
response(trans("Error_extension").AddErrorLocation(), 406)->send(); //line 260
exit();
}
}
Server issues:
On the server, those two issues are replaced by this single error:
Not enough Memory
(#/home/site/public_html/webroot/3rdparty/responsive file manager/filemanager.upload.php#241)
which refers to this set of if statements:
if ( ! empty($_FILES) || isset($_POST['url']))
{
if (in_array(fix_strtolower($extension), $ext))
{
if ($is_img)
{
$memory_error = FALSE;
if ( $extension != 'svg' && !create_img($targetFile, $targetFileThumb, 122, 91))
{
$memory_error = TRUE;
}
// not enough memory
if ($memory_error)
{
unlink($targetFile);
response(trans("Not enought Memory").AddErrorLocation(), 406)->send(); //line 241
exit();
}
}
}
}
Attempts so far:
I've looked at the following:
With the file extensions issue on my local machine, I checked the allowed file extensions in the config.php file, but both formats of jpeg were already there:
'ext_img' => array( 'jpg', 'jpeg', 'png', 'gif', 'bmp', 'tiff', 'svg' ), //Images
Meanwhile in include\mime_type_lib.php, both formats of jpeg were already there:
$mime_types = array(
'jpeg' => 'image/jpeg',
'jpg' => 'image/jpeg',
)
On my local machine, I increased the upload_max_filesize to 128M. Meanwhile on the server, I used cPanel's PHP settings to do the same thing. Additionally in the config.php file, I changed the MaxSizeUpload setting to match the above changes as follows:
'MaxSizeUpload' => 128,
I did also check against the latest version of config.php and upload.php to see if my versions were outdated, but that wasn't the case.

Try this:
if ( ! empty($_FILES) || isset($_POST['url']))
{
if(isset($_POST['url'])){
if(FALSE === ($temp = tempnam('/tmp','RF'))){
response(trans("Failed to create temporary file").AddErrorLocation(), 406)->send();
exit();
}
$handle = fopen($temp, "w");
fwrite($handle, file_get_contents($_POST['url']));
fclose($handle);
$explUrl = explode(".", basename($_POST['url']));
$suffix = array_pop($explUrl);
$_FILES['file']= array(
'name' => basename($_POST['url']),
'tmp_name' => $temp,
'size' => filesize($temp),
// type should be mime-type not file suffix
'type' => $suffix,
'error' => UPLOAD_ERR_OK
);
}
if($_FILES['file']['error'] !== UPLOAD_ERR_OK){
response(trans("Error upload code: ".$_FILES['file']['error']).AddErrorLocation(), 406)->send();
// error code list: http://php.net/manual/en/features.file-upload.errors.php
exit();
}
if(empty($_FILES['file']['tmp_name'])){
response(trans("Error upload").AddErrorLocation(), 406)->send();
exit();
}
$info = pathinfo($_FILES['file']['name']);
$mime_type = $_FILES['file']['type'];
if (function_exists('mime_content_type')){
$mime_type = mime_content_type($_FILES['file']['tmp_name']);
}
}
