本文实例讲述了PHP设置头信息及取得返回头信息的方法。分享给大家供大家参考，具体如下：

设置请求的头信息，我们可以用header函数，可以用fsockopen,可以用curl等，本文主要讲的是用curl来设置头信息，并取得返回后的头信息。

一、请求方设置自己的头信息，header.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

<?php function FormatHeader($url, $myIp = null,$xml = null) {  // 解悉url  $temp = parse_url($url);  $query = isset($temp['query']) ? $temp['query'] : '';  $path = isset($temp['path']) ? $temp['path'] : '/';  $header = array (  "POST {$path}?{$query} HTTP/1.1",  "Host: {$temp['host']}",  "Content-Type: text/xml; charset=utf-8",  'Accept: */*',  "Referer: http://{$temp['host']}/",  'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)',  "X-Forwarded-For: {$myIp}",  "Content-length: 380",  "Connection: Close"  );  return $header; } $interface = 'http://localhost/test/header2.php'; $header = FormatHeader($interface,'10.1.11.1'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $interface); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 curl_setopt($ch, CURLOPT_TIMEOUT, 5); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); var_dump($result); ?>

二、被请求方，取得头信息，header2.php

?

1 2 3

<?php print_r($_SERVER); //头信息里面有内容绝大部分是放在系统变量里面的 ?>

三、看一下header.php请求的结果

?

1 2 3 4 5 6 7 8 9 10 11 12 13

string(1045) "Array ( [HTTP_HOST] => localhost [CONTENT_TYPE] => text/xml; charset=utf-8 [HTTP_ACCEPT] => */* [HTTP_REFERER] => http://localhost/ [HTTP_USER_AGENT] => Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1) [HTTP_X_FORWARDED_FOR] => 10.1.11.1 [CONTENT_LENGTH] => 380 [PATH] => /usr/local/bin:/usr/bin:/bin [SERVER_SIGNATURE] => <address>Apache/2.2.16 (Ubuntu) Server at localhost Port 80</address> 。。。。。。。。。。。。。。。。。。。。。。。。。。。。 )

上面那几个，我们可以明显看到，是我设置的头信息。

四、取得返回的头信息

复制代码 代码如下:

curl_setopt($ch, CURLOPT_HEADER, 1); //取得返回头信息

我们把CURLOPT_HEADER设置成1，在取得的结果当中，显示数组的前面会有这些信息

?

1 2 3 4 5 6 7 8 9 10 11 12

string(1239) "HTTP/1.1 200 OK Date: Fri, 27 May 2011 01:57:57 GMT Server: Apache/2.2.16 (Ubuntu) X-Powered-By: PHP/5.3.3-1ubuntu9.5 Vary: Accept-Encoding Content-Length: 1045 Content-Type: text/html Array (  [HTTP_HOST] => localhost  [CONTENT_TYPE] => text/xml; charset=utf-8  [HTTP_ACCEPT] => */*

五、$_SERVER部分头信息是拿不到的

修改一下header.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43

<?php function FormatHeader($url, $myIp = null,$xml = null) {  // 解悉url  $temp = parse_url($url);  $query = isset($temp['query']) ? $temp['query'] : '';  $path = isset($temp['path']) ? $temp['path'] : '/';  $header = array (  "POST {$path}?{$query} HTTP/1.1",  "Host: {$temp['host']}",  "Content-Type: text/xml; charset=utf-8",  'Accept: */*',  "Referer: http://{$temp['host']}/",  'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)',  "X-Forwarded-For: {$myIp}",  "Content-length: " . strlen($xml) ."\r\n\r\n" .$xml, //修改1  "Connection: Close"  );  return $header; } $xml = '<?xml version="1.0" encoding="utf-8"?> //修改2  <profile>  <sha1>adsfadsf</sha1>  <user_id>asdfasdf</user_id>  <album_id>asdf</album_id>  <album_name>asdf</album_name>  <tags>asdfasd</tags>  <title>asdfasdf</title>  <content>asdfadsf</content>  <type>asdfasdf</type>  <copyright>asdfasdf</copyright>  </profile>'; $interface = 'http://localhost/test/header2.php'; $header = FormatHeader($interface,'10.1.11.1',$xml); //修改3 $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $interface); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 curl_setopt($ch, CURLOPT_TIMEOUT, 5); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); var_dump($result); ?>

如果这样的话，header2.php里面，打印$_SERVER不可能把头信息中的xml打印出来。这个时候，我们在header2.php后面加上以下二行

?

1 2	$raw_post_data = file_get_contents('php://input', 'r'); var_dump($raw_post_data);

这样就可以取到$xml的内容，并且只会取$xml的内容。
