How to get only the http status code of the accessed page in Php_PHP Tutorial

In certain situations, it is often necessary to obtain the http status code of the accessed page without returning the content of the page. How can such a function be achieved? Please see the key code below:




[php] Function GetHttpStatusCode($url){
            $curl = curl_init();
​​​​ curl_setopt($curl,CURLOPT_URL,$url);//Get content url
​​​​ curl_setopt($curl,CURLOPT_HEADER,1);//Get http header information
           curl_setopt($curl,CURLOPT_NOBODY,1);//Does not return html body information
           curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);//Return the data stream, no direct output
            curl_setopt($curl,CURLOPT_TIMEOUT,30); //Timeout duration, unit seconds
          curl_exec($curl);
            $rtn= curl_getinfo($curl,CURLINFO_HTTP_CODE);
           curl_close($curl);
return }
$url="http://www.BkJia.com";
echo GetHttpStatusCode($url);                                                                        ?>
function GetHttpStatusCode($url){
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,$url);//Get content url
curl_setopt($curl,CURLOPT_HEADER,1);//Get http header information
curl_setopt($curl,CURLOPT_NOBODY,1);//Does not return html body information
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);//Return the data stream, do not output directly
curl_setopt($curl,CURLOPT_TIMEOUT,30); //Timeout duration, unit seconds
curl_exec($curl);
$rtn= curl_getinfo($curl,CURLINFO_HTTP_CODE);
curl_close($curl);
Return $rtn;
}
$url="http://www.BkJia.com";
echo GetHttpStatusCode($url);                                                                      ?>

If Baidu can be accessed normally, of course the result of running the above code will be 200.
