PHP利用curl上传文件到FTP服务器(无ftp扩展情况下)

在一次需求中,需要一个FTP服务器作为中转站,程序定时在FTP服务器获取数据,定时上传数据库的数据到FTP服务器上,由于PHP没有安装ftp扩展,导致FTP操作很是麻烦,对于socket的理解不够深入,由于时间比较紧急,在同事指点下,想到了用curl方法,经过自己的整理,将curl方法整理为一个类:

<?php/* * To change this template, choose Tools | Templates * ftp curl方法操作类 */class ftp{    //FTP服务器地址    public static $host = "127.0.0.1";    //FTP端口    public static $port = "2121";    //上传的FTP目录    public static $uploaddir = "upblod";    //读取的FTP目录    public static $readdir = "read";    //FTP用户名    public static $usrname = "user";    //FTP密码    public static $pwd = "pwd";    /*     * curl 方法将文件上传到FTP服务器     * $filename上传到FTP的文件名,$uploadfile具体需要上传文件的地址(我用的绝对路径)     */    public static function ftp_upload($filename,$uploadfile)    {        $url = "ftp://".self::$host.":".self::$port."/".self::$uploaddir."/".$filename;        //需要上传的文件        $fp = fopen ($uploadfile, "r");         $ch = curl_init();         curl_setopt($ch, CURLOPT_VERBOSE, 1);  //有意外发生则报道         curl_setopt($ch, CURLOPT_USERPWD, self::$usrname.':'.self::$pwd); //FTP登陆账号密码,模拟登陆         curl_setopt($ch, CURLOPT_URL, $url);         curl_setopt($ch, CURLOPT_PUT, 1); //用HTTP上传一个文件         curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //不输出         curl_setopt($ch, CURLOPT_INFILE, $fp); //要上传的文件         $http_result = curl_exec($ch); //执行         $error = curl_error($ch);         curl_close($ch);         fclose($fp);        //成功上传文件 返回true        if (!$error)         {             return true;        }     }    /*     * curl 方法将读取FTP文件并保存在本地使用     * $filenameFTP服务器文件名,$filepath 保存到本地(服务器)的目录     */        public static function ftp_read($filename,$filepath)    {               $curl = curl_init();                 $target_ftp_file = "ftp://".self::$host.":".self::$port."/".self::$readdir."/".$filename;//完整路径                curl_setopt($curl, CURLOPT_URL,$target_ftp_file);        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($curl, CURLOPT_VERBOSE, 1);        curl_setopt($curl, CURLOPT_FTP_USE_EPSV, 0);        curl_setopt($curl, CURLOPT_TIMEOUT, 300); // times out after 300s        curl_setopt($curl, CURLOPT_USERPWD,self::$usrname.':'.self::$pwd);//FTP用户名:密码        // Sets up the output file        //本地保存目录        if(is_dir($filepath)){         $outfile = fopen($filepath.$filename, 'w');//保存到本地的文件名         curl_setopt($curl,CURLOPT_FILE,$outfile);         // Executes the cURL          $info = curl_exec($curl);         fclose($outfile);         $error_no = curl_errno($curl);         curl_close($curl);         //成功读取文件,返回 true         if($info){             return true;         }        }             }}?>

?这里只是做了上传与下载文件,删除文件的操作没有涉及,有兴趣的童鞋可以研究下
