I am trying to save **files** from **one folder** to **another. zip folder** placed in different directory. And I have written the following codes: 

**archive.php** 

```
<?php
    $zip = new ZipArchive();
    $zip->open('example.zip',  ZipArchive::CREATE);
    $srcDir = "/home/sam/uploads/";
    $files= scandir($srcDir);
    //var_dump($files);
    unset($files[0],$files[1]);
    foreach ($files as $file) {
        $zip->addFile("{$file}");    
    }
    $zip->close();
?>

```

But sadly I am not able to create the .zip folder. Is there any step I missed?
