php處理http post/get請求

• 判斷請求類型

$_SERVER[‘REQUEST_METHOD’]
此變數中儲存的是表單提交的方式

<code><span>$method</span> =<span>$_SERVER</span>[<span>'REQUEST_METHOD'</span>];
<span>$data</span> = <span>''</span>;
<span>if</span> (<span>$method</span> == <span>'GET'</span>)
{
    <span>$data</span> = <span>$_SERVER</span>[<span>'QUERY_STRING'</span>];
}
<span>else</span><span>if</span> (<span>$method</span> == <span>'POST'</span>)
{
    <span>$data</span> = file_get_contents(<span>"php://input"</span>);
}
<span>else</span>
{
    <span>$logger</span>-><span>error</span>(<span>'unknown http method. url: '</span> . <span>$_SERVER</span>[<span>'REQUEST_URI'</span>]);
}</code>

• 取得URL參數

<code><span>//获取域名或主机地址 </span><span>echo</span><span>$_SERVER</span>[<span>'HTTP_HOST'</span>].<span>"<br>"</span>; <span>#localhost</span><span>//获取网页地址 </span><span>echo</span><span>$_SERVER</span>[<span>'PHP_SELF'</span>].<span>"<br>"</span>; <span>#/blog/testurl.php</span><span>//获取网址参数 </span><span>echo</span><span>$_SERVER</span>[<span>"QUERY_STRING"</span>].<span>"<br>"</span>; <span>#id=5</span><span>//获取用户代理 </span><span>echo</span><span>$_SERVER</span>[<span>'HTTP_REFERER'</span>].<span>"<br>"</span>; 

<span>//获取完整的url</span><span>echo</span><span>'http://'</span>.<span>$_SERVER</span>[<span>'HTTP_HOST'</span>].<span>$_SERVER</span>[<span>'REQUEST_URI'</span>];
<span>echo</span><span>'http://'</span>.<span>$_SERVER</span>[<span>'HTTP_HOST'</span>].<span>$_SERVER</span>[<span>'PHP_SELF'</span>].<span>'?'</span>.<span>$_SERVER</span>[<span>'QUERY_STRING'</span>];


<span>//包含端口号的完整url</span><span>echo</span><span>'http://'</span>.<span>$_SERVER</span>[<span>'SERVER_NAME'</span>].<span>':'</span>.<span>$_SERVER</span>[<span>"SERVER_PORT"</span>].<span>$_SERVER</span>[<span>"REQUEST_URI"</span>]; 


<span>//只取路径</span><span>$url</span>=<span>'http://'</span>.<span>$_SERVER</span>[<span>'SERVER_NAME'</span>].<span>$_SERVER</span>[<span>"REQUEST_URI"</span>]; 
<span>echo</span> dirname(<span>$url</span>);</code>
