Unzip a file with php

I want to unzip a file and this works fine

system('unzip File.zip');

But I need to pass in the file name through the URL and can not get it to work, this is what I have.

$master = $_GET["master"];
system('unzip $master.zip');

What am I missing? I know it has to be something small and stupid I am overlooking.

Thank you,

Use below PHP code, with file name in the URL param "name"

<?php

$fileName = $_GET['name'];

if (isset($fileName)) {


    $zip = new ZipArchive;
    $res = $zip->open($fileName);
    if ($res === TRUE) {
      $zip->extractTo('./');
      $zip->close();
      echo 'Extracted file "'.$fileName.'"';
    } else {
      echo 'Cannot find the file name "'.$fileName.'" (the file name should include extension (.zip, ...))';
    }
}
else {
    echo 'Please set file name in the "name" param';
}

?>

Using getcwd() to extract in the same directory

<?php
$unzip = new ZipArchive;
$out = $unzip->open('wordpress.zip');
if ($out === TRUE) {
  $unzip->extractTo(getcwd());
  $unzip->close();
  echo 'File unzipped';
} else {
  echo 'Error';
}
?>

PHP has its own inbuilt class that can be used to unzip or extracts contents from a zip file. The class is ZipArchive. Below is the simple and basic PHP code that will extract a zip file and place it in a specific directory:

<?php
$zip_obj = new ZipArchive;
$zip_obj->open('dummy.zip');
$zip_obj->extractTo('directory_name/sub_dir');
?>

If you want some advance features then below is the improved code that will check if the zip file exists or not:

<?php
$zip_obj = new ZipArchive;
if ($zip_obj->open('dummy.zip') === TRUE) {
   $zip_obj->extractTo('directory/sub_dir');
   echo "Zip exists and successfully extracted";
}
else {
   echo "This zip file does not exists";
}
?>

Simply try this yourDestinationDir is the destination to extract to or remove -d yourDestinationDir to extract to root dir.

$master = 'someDir/zipFileName';
$data = system('unzip -d yourDestinationDir '.$master.'.zip');

I updated answer of @rdlowrey to a cleaner and better code, This will unzip a file into current directory using __DIR__.

<?php 
    // config
    // -------------------------------
    // only file name + .zip
    $zip_filename = "YOURFILENAME.zip";
?>

<!DOCTYPE html>
<html>
<head>
    <meta charset='utf-8' >
    <title>Unzip</title>
    <style>
        body{
            font-family: arial, sans-serif;
            word-wrap: break-word;
        }
        .wrapper{
            padding:20px;
            line-height: 1.5;
            font-size: 1rem;
        }
        span{
            font-family: 'Consolas', 'courier new', monospace;
            background: #eee;
            padding:2px;
        }
    </style>
</head>
<body>
    <div class="wrapper">
        <?php
        echo "Unzipping <span>" .__DIR__. "/" .$zip_filename. "</span> to <span>" .__DIR__. "</span><br>";
        echo "current dir: <span>" . __DIR__ . "</span><br>";
        $zip = new ZipArchive;
        $res = $zip->open(__DIR__ . '/' .$zip_filename);
        if ($res === TRUE) {
          $zip->extractTo(__DIR__);
          $zip->close();
          echo '<p style="color:#00C324;">Extract was successful! Enjoy ;)</p><br>';
        } else {
          echo '<p style="color:red;">Zip file not found!</p><br>';
        }
        ?>
        End Script.
    </div>
</body>
</html>

Just use this:

  $master = $_GET["master"];
  system('unzip' $master.'.zip');

in your code $master is passed as a string, system will be looking for a file called $master.zip

  $master = $_GET["master"];
  system('unzip $master.zip'); `enter code here`
