    $archive = new PclZip($file); 
    if ($archive->extract(PCLZIP_OPT_PATH, $destination_dir) == 0) {

Answer 2

$destination_dir = "/foo/bar"; 

    if (file_exists($destination_dir)) { $destination_dir = "/foo/bar2"; } 

    mkdir($destination_dir); 

    $archive = new PclZip($file); 
    if ($archive->extract(PCLZIP_OPT_PATH, $destination_dir) == 0) { 
     die("Unzip failed. Error : ".$archive->errorInfo(true)); 
    } 
    echo "Successfully extracted files to ".$destination_dir;
