php使用cURL上传图片

上传文件和POST非常相似，都是通过表单采取POST方法提交的。

先新建一个接收文件的页面upload.php:

var_dump($_POST);
var_dump($_FILES);

再建立一个发送文件的test.php

$post_data = array(
    ‘name‘ => ‘chenqionghe‘,
    ‘logo‘ => ‘@E:\test.jpg‘,
    ‘face‘ => ‘handsome‘
);
//1.初始化
$ch = curl_init();
//2.设置选项，包括URL
curl_setopt($ch, CURLOPT_URL,"http://localhost/upload.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
//3.执行并获取内容
$output = curl_exec($ch);
//4.释放curl句柄
//$info = curl_getinfo($ch);//获取一个cURL连接资源句柄的信息
curl_close($ch);
echo $output;

访问test.php，显示结果如下

array (size=2)
  ‘name‘ => string ‘chenqionghe‘ (length=11)
  ‘face‘ => string ‘handsome‘ (length=8)
array (size=1)
  ‘logo‘ =>
    array (size=5)
      ‘name‘ => string ‘test.jpg‘ (length=8)
      ‘type‘ => string ‘application/octet-stream‘ (length=24)
      ‘tmp_name‘ => string ‘D:\Wamp\tmp\php67A3.tmp‘ (length=23)
      ‘error‘ => int 0
      ‘size‘ => int 57083
