How to unzip a file using PHP ?

To unzip a file with PHP, we can use the ZipArchive class. ZipArchive is a simple utility class for zipping and unzipping files. We don't require any extra additional plugins for working with zip files. ZipArchive class provides us a facility to create a zip file or to extract the existing zip file. The ZipArchive class has a method called extractTo to extract the contents of the complete archive or the given files to the specified destination. The ZipArchive class also has a lot of other methods and properties to help you get more information about the archive before extracting all its contents. Syntax:

bool ZipArchive::extractTo( string $destination, mixed $entries )

Parameters:

• destination: The $destination parameter can be used to specify the location where to extract the files.
• entries: The $entries parameter can be used to specify a single file name which is to be extracted, or you can use it to pass an array of files.

Example 1: This example unzip all the files from specific folder. php

<?php

$zip = new ZipArchive;

// Zip File Name
if ($zip->open('GeeksforGeeks.zip') === TRUE) {

    // Unzip Path
    $zip->extractTo('/Destination/Directory/');
    $zip->close();
    echo 'Unzipped Process Successful!';
} else {
    echo 'Unzipped Process failed';
}
?>

Description: Create an object of the ZipArchive class and open a given zip file using $zip->open() method. If it returns TRUE then extract the file to the specified path with extractTo() method by passing path address as an argument in it. Example 2: This example unzip the specific file from the folder. php

<?php

$zip = new ZipArchive;

// Zip File Name
$res = $zip->open('GeeksForGeeks.zip');

if ($res === TRUE) {
    
    // Unzip Path 
    $zip->extractTo('/Destination/Directory/',
        array('H_W.gif', 'helloworld.php'));
        
    $zip->close();
    echo 'Unzipped Process Successful!';
} else {
    echo 'Unzipped Process failed';
}

Description: With the file element, you can select the zip file that you want to extract. If a selected file is valid then pass to open() method and extract it to the specified path using extractTo() method.
