PHP警告：ZipArchive :: extractTo（）：权限被拒绝错误

Question

我发现这个代码带有一个zip文件并将其解压缩。但是我遇到了一些错误。当我尝试上传zip时，我收到此错误Warning: ZipArchive::extractTo(): Permission denied in /Applications/XAMPP/xamppfiles/htdocs/newLosani/testphp.php on line 26我将文件和文件夹的权限更改为777和644，但都没有工作：（

我甚至尝试将我上传到777的文件的权限更改为无效。

以下是相关代码：

<?php
if($_FILES["zip_file"]["name"]) {
        $filename = $_FILES["zip_file"]["name"];
        $source = $_FILES["zip_file"]["tmp_name"];
        $type = $_FILES["zip_file"]["type"];

        $name = explode(".", $filename);
        $accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/x-compressed');
        foreach($accepted_types as $mime_type) {
                if($mime_type == $type) {
                        $okay = true;
                        break;
                }
        }

        $continue = strtolower($name[1]) == 'zip' ? true : false;
        if(!$continue) {
                $message = "The file you are trying to upload is not a .zip file. Please try again.";
        }

        $target_path = $filename;  // change this to the correct site path
        if(move_uploaded_file($source, $target_path)) {
                $zip = new ZipArchive();
                $x = $zip->open($target_path);
                if ($x === true) {
                        $zip->extractTo("/zip/"); // change this to the correct site path
                        $zip->close();

                        unlink($target_path);
                }
                $message = "Your .zip file was uploaded and unpacked.";
        } else {
                $message = "There was a problem with the upload. Please try again.";
        }
        echo $message;
}
?>
