获取http内容的php函数

实现获取http内容的php函数。

代码如下:

<?php

function http_open($url, $data, $cookie = null, $method = "GET", $timeout = 60) {

$options = array();

$options['http']['method'] = $method;

$options['http']['user_agent'] = $_SERVER['HTTP_USER_AGENT'];

$options['http']['timeout'] = $timeout;

if($method == "POST") : 

$length = strlen($data);

//  www.jbxue.com

$options['http']['header'] = "Content-type: application/x-www-form-urlencoded\r\n".

"Content-Length: {$length}\r\n".

"P3P: CP=\"CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR\"\r\n".

"cookie: {$cookie}\r\n".

"Connection: close\r\n";

$options['http']['content'] = $data;

else:

$options['http']['header'] = "Content-type: application/x-www-form-urlencoded\r\n".

"P3P: CP=\"CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR\"\r\n".

"cookie: {$cookie}\r\n".

"Connection: close\r\n";

endif;



$context = stream_context_create($options);

return file_get_contents($url, 0, $context);

}

echo http_open("http://www.jbxue.com/1.php", "username=haowei", "id=5", "POST");
