Expanding the answer from Bernhard (credits to him) you can do regular checks like if (count ($result) > 0){ //your code } — Mbotet, Jan 14 '19 at 14:19

Use the glob() function.

$result = glob("my/folder/uploads/*.zip");

It will return an array with the *.zip-files.

This also could help, using scandir and pathinfo

 /**
 * 
 * @param string $directoryPath the directory to scan
 * @param string $extension the extintion e.g zip
 * @return []
 */
function getFilesByExtension($directoryPath, $extension)
{

    $filesRet = [];
    $files = scandir($directoryPath);
    if(!$files) return $filesRet;
    foreach ($files as $file) {
        if(pathinfo($file)['extension'] === $extension) 
            $filesRet[]= $file; 
    }

    return $filesRet;
}

it can be used like

 var_dump(getFilesByExtension("uploads/","zip"));

Answer is already given by @Bemhard, i am adding more information for future use:

If you want to run script inside your uploads folder than you just need to call glob('*.zip').

<?php
foreach(glob('*.zip') as $file){
    echo $file."<br/>";
}
?>

If you have multiple folders and containing multiple zip files inside the folders, than you just need to run script from root.

<?php
$dir = __DIR__; // will get the exact path
$dirs = array_filter(glob('*'), 'is_dir'); // filter is directory or not.

$i = 1;
foreach ($dirs as $key => $value) {
    foreach(glob($value.'/*.zip') as $file){
        echo $file."<br/>"; // this will print all files inside the folders.
    }   
    $i++;
}
?>

One Extra point, if you want to remove all zip files with this activity, than you just need to unlink file by:

<?php
$dir = __DIR__; // will get the exact path
$dirs = array_filter(glob('*'), 'is_dir'); // filter is directory or not.

$i = 1;
foreach ($dirs as $key => $value) {
    foreach(glob($value.'/*.zip') as $file){
        echo $file."<br/>"; // this will print all files inside the folders.
        unlink($file); // this will remove all files.
    }   
    $i++;
}
?>
