i am trying to extract the contents of a zipped folder into the root of the website i have a directory called zip.zip but everything i try creates a directory called zip, is there a way to extract the contents into the root

<?php
$zip = new ZipArchive;
    if ($zip->open("zip.zip")){
        $path = getcwd() . "/";
        $path = str_replace("\\","/",$path);
        echo $path;
        echo $zip->extractTo($path);
        $zip->close();
        echo 'Done.';
    } else {
        echo "Error";
    }
?>

I have solved this

<?php

$path = 'zip.zip';

$zip = new ZipArchive;
if ($zip->open($path) === true) {
    for($i = 0; $i < $zip->numFiles; $i++) {
        $filename = $zip->getNameIndex($i);
        $fileinfo = pathinfo($filename);
        copy("zip://".$path."#".$filename, "".$fileinfo['basename']);
    }                  
    $zip->close();                  
}

?>
