Answer 1

你可以简单地使用PHP FTP 做到这一点见下文代码 -

$connection = ftp_connect($server); 

$login = ftp_login($connection, $ftp_user_name, $ftp_user_pass); 

    if (!$connection || !$login) { die('Connection attempt failed!'); } 

$upload = ftp_put($connection, $dest, $source, $mode); 

    if (!$upload) { echo 'FTP upload failed!'; } 

ftp_close($connection);

试试这个代码：

if (version_compare(phpversion(), '5.5.0', '>=')) 
    { 
     $postData['file'] = new CURLFile($fileData['tmp_name'], $fileData['type'] ,$fileData['name']); 
    } 
    else 
    { 
     $postData['file'] = '@'.$fileData['tmp_name']; 
     $postData['file_info']['name'] = $fileData['name']; 
    } 

    $url = 'http://your-site.com/'; 

    $ch = curl_init(); 

    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_POST,1); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); 

    $output= curl_exec($ch); 

    if ($output === false) 
    { 
     //handle the error 
    } 

    curl_close ($ch); 

注意：如果你有PHP 5.5及更高版本，建议使用CURLFile。

以下代码可能会有所帮助。

<?php 
$target="http://youraddress.tld/example/upload.php"; 

# http://php.net/manual/en/curlfile.construct.php 

// Create a CURLFile object/procedural method 
$cfile = curl_file_create('resource/test.png','image/png','testpic'); // try adding 

// Create a CURLFile object/oop method 
#$cfile = new CURLFile('resource/test.png','image/png','testpic'); // uncomment and use if the upper procedural method is not working. 

// Assign POST data 
$imgdata = array('myimage' => $cfile); 

$curl = curl_init(); 
curl_setopt($curl, CURLOPT_URL, $target); 
curl_setopt($curl, CURLOPT_USERAGENT,'Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15'); 
curl_setopt($curl, CURLOPT_HTTPHEADER,array('User-Agent: Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15','Referer: http://someaddress.tld','Content-Type: multipart/form-data')); 
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // stop verifying certificate 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curl, CURLOPT_POST, true); // enable posting 
curl_setopt($curl, CURLOPT_POSTFIELDS, $imgdata); // post images 
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); // if any redirection after upload 
$r = curl_exec($curl); 
curl_close($curl); 

?>
