PHP通过Curl发送文件到远程服务器

php_curl.php

<?php
$file = array("upimg"=>"@E:/www/jdt.html");//文件路径，前面要加@，表明是文件上传.
$curl = curl_init("http://域名/server.php");
curl_setopt($curl,CURLOPT_POST,true);
curl_setopt($curl,CURLOPT_POSTFIELDS,$file);
curl_exec($curl);

?>

server.php

<?php
echo "<pre>";
print_r($_FILES);
echo "</pre>";

if(move_uploaded_file($_FILES['file']['tmp_name'],'./test.txt')){
 echo 'ok';
}
?>
