　　一、关于使用curl来进行文件上传
　　curlupload.php

<?php
$url = 'http://localhost/test/upload.php';
$post_data = array('title'=>'xx','pic'=>'@D:/wamp/www/test/1.png');
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_data);
$out = curl_exec($ch);
curl_close($ch);
echo $out;
?>
　　upload.php

<?php
var_dump($_FILES);
?>
　　结果

array (size=1)
'pic' =>
array (size=5)
'name' => string '1.png' (length=5)
'type' => string 'application/octet-stream' (length=24)
'tmp_name' => string 'D:\wamp\tmp\phpCA72.tmp' (length=23)
'error' => int 0
'size' => int 1014951
　　二、通过curl请求一张网页
　　curl.php

<?php
// 创建一个新cURL资源
$ch = curl_init("http://www.baidu.com");
// 设置URL和相应的选项
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// 检查是否有错误发生
if(!curl_errno($ch))
{
$info = curl_getinfo($ch);
var_dump($info);
}
// 抓取URL并把它传递给浏览器
$html = curl_exec($ch);
// 关闭cURL资源，并且释放系统资源
curl_close($ch);
?>
　　结果

array (size=26)
'url' => string 'http://www.baidu.com' (length=20)
'content_type' => null
'http_code' => int 0
'header_size' => int 0
