PHP中FTP相关函数小结

　　本文实例讲述了PHP中FTP相关函数。分享给大家供大家参考，具体如下：

　　 <?php set_time_limit(0); //转存本地地址 define( STORE_PATH, dirname(__FILE__) . /../../../../temp_data/test/ ); define(LIST_PATH, STORE_PATH . list/); define(CHAPTER_PATH, LIST_PATH . chapter/); define(DETAIL_PATH, LIST_PATH . detail/); createFolder(STORE_PATH); createFolder(LIST_PATH); createFolder(CHAPTER_PATH); createFolder(DETAIL_PATH); $ftp_server = ip; $ftp_user = anonymous; $ftp_pass = anonymous; $conn_id = ftp_connect ( $ftp_server ) or die ( Couldnt connect to $ftp_server ); if (@ftp_login ( $conn_id, $ftp_user, $ftp_pass )) { echo Connected as $ftp_user@$ftp_server\n; } else { echo Couldnt connect as $ftp_user\n; } ftp_pasv($conn_id, true); /** * 创建文件并写入内容 * * @param string $path path/ * @param string $fileName filename * @param string $data content * * @return string 返回路径 */ function createFile ($path, $fileName, $data) { if (empty($data)) { return false; } file_put_contents($path . $fileName, $data); return $path . $fileName; } /** * 创建目录 * * @param string $path path * * @return no */ function createFolder ($path) { if (!
