php中可以通过curl来模拟http请求,同时可以获取http response header和body,当然也设置参数可以只获取其中的某一个,当设置同时获取response header和body时候,它们会一同作为结果返回,这时需要我们自己来分离它们。

下面代码是模拟向google一个http GET请求,代码如下:

<?php
function httpGet() { 
    $url = &#39;http://www.google.com.hk&#39;; 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_HEADER, TRUE);    //表示需要response header 
    curl_setopt($ch, CURLOPT_NOBODY, FALSE); //表示需要response body 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE); 
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 120); 
    $result = curl_exec($ch); 
    if (curl_getinfo($ch, CURLINFO_HTTP_CODE) == &#39;200&#39;) { 
        return $result; 
    } 
    return NULL; 
}
?>

调用上述方法后看到如下类似输出：
