使用opendir（）

Question

我正在创建一个wordpress插件，现在我收到了像

这样的错误

Warning: opendir(http://localhost/wordpress/wp-content/uploads/): failed to open dir: not implemented in http://localhost/wordpress/wp-content/plugins/my-plugin/FlxZipArchive.php on line 37
Warning: readdir() expects parameter 1 to be resource, boolean given in http://localhost/wordpress/wp-content/plugins/my-plugin/FlxZipArchive.php on line 38

这些是文件

的index.php

<?php

$upload_dir = wp_upload_dir();
$folder_name = $upload_dir['baseurl'];

//Don't forget to remove the trailing slash
$the_folder =$foldername;
$zip_file_name =  WP_CONTENT_DIR."/".'uploads.zip';
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE) {
    $za->addDir($the_folder, basename($the_folder));
    $za->close();
}
else
    echo 'Could not create a zip archive';
?>

FlxZipArchive.php

<?
/**
* FlxZipArchive, Extends ZipArchiv.
* Add Dirs with Files and Subdirs.
*
* <code>
*  $archive = new FlxZipArchive;
*  // .....
*  $archive->addDir( 'test/blub', 'blub' );
* </code>
*/
class FlxZipArchive extends ZipArchive {
    /**
     * Add a Dir with Files and Subdirs to the archive
     *
     * @param string $location Real Location
     * @param string $name Name in Archive
     * @author Nicolas Heimann
     * @access private
     **/
    public function addDir($location, $name) {
        $this->addEmptyDir($name);
        $this->addDirDo($location, $name);
     } // EO addDir;
    /**
     * Add Files & Dirs to archive.
     *
     * @param string $location Real Location
     * @param string $name Name in Archive
     * @author Nicolas Heimann
     * @access private
     **/
    private function addDirDo($location, $name) {
        $name .= '/';
        $location .= '/';
        // Read all Files in Dir
        $dir = opendir ($location);
        while ($file = readdir($dir))
        {
            if ($file == '.' || $file == '..') continue;
            // Rekursiv, If dir: FlxZipArchive::addDir(), else ::File();
            $do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
            $this->$do($location . $file, $name . $file);
        }
    } // EO addDirDo();
}
?>

每次执行index.php时，只需创建一个包含空文件夹的zip文件并退出

请有人帮我解决此错误

opendir()旨在打开本地目录（file://协议），自PHP 5.0.0 FTP（ftp://）

您似乎正在尝试传递一个URL（http://协议），该协议不是opendir的有效参数
