How to remove __MACOSX while using ZipArchive - php

Question

After hours of trying to figure out why php "ZipArchive" does not work as expected, due to Mac OS adding a "__MACOSX" folder in the zip compression process.
How would I go about deleting "__MACOSX" folder in a zip archive during the upload process in a form?
Below is what I'm working with:
<?php
public function uploadZip($file)
{
$advert_index;
$zip = new \ZipArchive;
if (true === $zip->open($file['tmp_name'])) {
$source = trim($zip->getNameIndex(0), '/');
for ($i = 0; $i < $zip->numFiles; $i++) {
$name = $zip->getNameIndex($i);
// Determine output filename (removing the `$source` prefix).
$substring_name = substr($name, strlen($source)+1);
$file = $this->option['uploads_path'] . $this->option['advert_id'] . '/' . $substring_name;
// Store the adverts `index.html` file URL to be returned.
if ('html' === pathinfo($name, PATHINFO_EXTENSION)) {
$advert_index = basename($name);
}
// Create the directories if necessary.
$dir = dirname($file);
if (! is_dir($dir)) {
mkdir($dir, 0777, true);
}
// Read from Zip and write to disk.
$fpr = $zip->getStream($name);
$fpw = fopen($file, 'w');
while ($data = fread($fpr, 1024)) {
fwrite($fpw, $data);
}
fclose($fpr);
fclose($fpw);
}
$zip->close();
return array(
'status' => true,
'message' => array(
'index' => $advert_index,
'type' => 'text/html', // #HACK: Set MIME type manually. #TODO: Read MIME type from file.
),
);
}
return array(
'status' => false,
'message' => 'Upload failed',
);
}
Any help would be much appreciated :)
Note: I Managed to find the file just can't get it to be removed.
// Check to see the __MACOSX
if($zip->getNameIndex($i) === "__MACOSX/") {
error_log($zip->getNameIndex($i) . ' - Error here continue');
$zip->deleteName("__MACOSX/");
continue; // Move on to the next iteration
// $zip->deleteIndex($i);
} else {
$name = $zip->getNameIndex($i);
}

It was actually very simple, instead to trying to delete the folder within the zip-archive just had to skip all indexes aka filename that begin with a certain string while looping through the files.
if(substr($zip->getNameIndex($i), 0, 9) === "__MACOSX/") {
continue;
} else {
$name = $zip->getNameIndex($i);
}
