Is 7-Zip a recommended tool for extracting files on a PHP server, and how can it be integrated for server-side usage?

7-Zip is not a recommended tool for extracting files on a PHP server as it is primarily a desktop application. Instead, PHP provides built-in functions like `zip_open()` and `zip_read()` for handling ZIP files. To extract files on a PHP server, you can use these functions to read the contents of a ZIP file and extract them accordingly.

$zip = zip_open('example.zip');

if ($zip) {
    while ($zip_entry = zip_read($zip)) {
        $entry_name = zip_entry_name($zip_entry);
        $entry_size = zip_entry_filesize($zip_entry);
        
        if (zip_entry_open($zip, $zip_entry, "r")) {
            $contents = zip_entry_read($zip_entry, $entry_size);
            file_put_contents($entry_name, $contents);
            zip_entry_close($zip_entry);
        }
    }
    
    zip_close($zip);
}
