<?php/** * 发送post请求 * @param string $url 请求地址 * @param array $post_data post键值对数据 * @return string */function send_post($url, $post_data) { $postdata = http_build_query($post_data); $options = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-type:application/x-www-form-urlencoded', 'content' => $postdata, 'timeout' => 15 * 60 // 超时时间（单位:s） ) ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return $result;} |

$post_data = array( 'username' => 'stclair2201', 'password' => 'handan'); |
实战经验：
当我利用上述代码给另一台服务器发送http请求时，发现，如果服务器处理请求时间过长，本地的PHP会中断请求，即所谓的超时中断，第一个怀疑的是PHP本身执行时间的超过限制，但想想也不应该，因为老早就按照这篇文章设置了“PHP执行时间限制”（【推荐】PHP上传文件大小限制大全 ），仔细琢磨，想想，应该是http请求本身的一个时间限制，于是乎，就想到了怎么给http请求时间限制搞大一点。。。。。。查看PHP手册，果真有个参数 “ timeout ”，默认不知道多大，当把它的值设大一点，问题得已解决，弱弱地做个笔记~~~
