PHP设置头信息及取得返回头信息的方法

<"POST {$path}",
 "Host: {$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);
"htmlcode">

<"htmlcode">

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


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


<"POST {$path}",
 "Host: {$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 = '<"1.0" encoding="utf-8""htmlcode">

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




这样就可以取到$xml的内容，并且只会取$xml的内容。
