PHP refusing to extract docx as zip from Windows/Temp - php

Question

$dir = "temp/docx";
$errors = array();
$zip = new ZipArchive;
if($zip->open($file_path) === false){
$errors[] = 'Failed to open file';
}
if (empty($errors)) {
$zip->extractTo($dir,"word/document.xml");
$zip->close();
$files = scandir($dir);
print_r($files);
Ok so, basically for some reason the extraction wont work. After seeing the folders empty, I decided to do a scandir to see if they were deleting after the php finished. Nothing. $files variable outputs nothing (ofcourse apart from .. and .).
The zip is actually a docx file, and after explicitly checking for errors, php seems to think the zip_open works, but I'm not sure if this is just a false positive.
I'm wondering if this is due to the fact this is actually a docx file and I need to explicitly save it as a zip file on the server. Or perhaps because this happens straight after being uploaded and the temp file gets deleted before being able to do anything with it (which I imagine is unlikely, as other formats work fine). Perhaps neither of my assumptions are close, or there's the chance I wrote the whole thing wrong. Any help?

Here you go:
<?php
/*Name of the document file*/
$document = 'demo.docx';
/*Directory*/
$dir = "temp/docx/";
/**Function to extract text*/
function extracttext($filename, $action) {
//Check for extension
$ext = end(explode('.', $filename));
//Check if DOCX file
if($ext == 'docx'){
$dataFile = "word/document.xml";
//else it's probebly an ODT file
} else {
$dataFile = "content.xml";
}
//Create a new ZIP archive object
$zip = new ZipArchive;
// Open the archive file
if (true === $zip->open($filename)) {
// If successful, search for the data file in the archive
if (($index = $zip->locateName($dataFile)) !== false) {
// Index found! Now read it to a string
$text = $zip->getFromIndex($index);
// Load XML from a string
// Ignore errors and warnings
$xml = DOMDocument::loadXML($text, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING);
if($action == "save"){
// Save xml to file
file_put_contents($dir ."word/document.xml", $xml->saveXML());
return "File succesfully saved.";
} else if($action == "text"){
// Remove XML formatting tags and return the text
return strip_tags($xml->saveXML());
}
}
//Close the archive file
$zip->close();
}
// In case of failure return a message
return "File not found";
}
//Save xml file
echo extracttext($document, "save");
//Echo text from file
echo extracttext($document, "text");
?>
