curl_setopt($curlobj, CURLOPT_HEADER, 0); 

curl_setopt($curlobj, CURLOPT_RETURNTRANSFER, 1);  

curl_setopt($curlobj, CURLOPT_TIMEOUT, 300); // times out after 300s

curl_setopt($curlobj, CURLOPT_USERPWD, "用户名:密码");//FTP用户名：密码

// Sets up the output file

$outfile = fopen('test.txt', 'wb');//保存到本地的文件名

curl_setopt($curlobj, CURLOPT_FILE, $outfile);



$rtn = curl_exec($curlobj);  

fclose($outfile); 

if(!curl_errno($curlobj)){

    echo "RETURN: " . $rtn;  

} else {

  echo 'Curl error: ' . curl_error($curlobj);

}

curl_close($curlobj);

上传:

<?php

$curlobj = curl_init();    

$localfile = 'test.php';

curl_setopt($curlobj, CURLOPT_UPLOAD, 1);

curl_setopt($curlobj, CURLOPT_INFILE, $fp);

curl_setopt($curlobj, CURLOPT_INFILESIZE, filesize($localfile));

$rtn = curl_exec($curlobj);  

fclose($fp); 

if(!curl_errno($curlobj)){

    echo "Uploaded successfully.";
