Why I cannot unzip a file using wildcards in PHP? - php

Question

I am trying to extract a zip-file using a wildcard. The point of this is to find out the said file. The file has a changing name after today's date when I download it: test-18-02-2016.zip. I tried like this:
<?php
$myFile = 'C:/Users/Acer/Downloads/test*.zip';
$zip = new ZipArchive();
if($zip->open($myFile) === true) {
$zip->extractTo('C:/Users/Acer/Downloads/');
$zip->close();
echo 'ok';
} else {
echo 'NOT ok!';
}
I am getting NOT ok ..of course, but when i switch on to test-18-02-2016.zipI get ok.
Any help to figure out why and how to resolve this is very appreciate it.

A ZipArchive can only represent one file at a time. If you absolutely must use wildcards, consider passing the wildcard string into glob() and using the results it returns.
For example:
$myFileList = glob('C:/Users/Acer/Downloads/test*.zip');
foreach ($myFileList as $myFile) {
echo 'Unzipping ' . $myFile . PHP_EOL;
$zip = new ZipArchive();
if($zip->open($myFile) === true) {
$zip->extractTo('C:/Users/Acer/Downloads/');
$zip->close();
echo 'ok';
} else {
echo 'NOT ok!';
}
}

I don't see anything in the documentation that says ZipArchive->open accepts a wildcard path in this way. Besides, what would happen if several files matched?
Instead, find the file you want. If it's today's date...
$myFile = 'C:/Users/Acer/Downloads/test-'.date("d-m-Y").'.zip';
