PHP sends custom data through the header

This article describes how to send custom data through the header. When sending a request, in addition to using the $_get/ $_post send data, you can also put the data in the header to transmit the past.

Send header:

We define three parameters, token, language, region, and send the past to the header.

    $url=' http://www.example.com ';$header=Array(' TOKEN:JXRAZEZAVM3HXM3D9PWNYIQQQC1SJBSU ',' Language:zh ',' Region:gz ');$content=Array(' name '=' Fdipzone ');$response= Tocurl ($url,$header,$content);$data= Json_decode ($response,true);Echo' POST data: ';Echo'
';p rint_r ($data[' Post ']); Echo '
';Echo' Header data: ';Echo'
';p rint_r ($data[' header ']); Echo '
';/** * Send data * @param String $url requested address * @param Array $header Custom Header data * @param Ar Ray $content Post Data * @return String * * functiontocurl($url, $header, $content){$ch= Curl_init ();if(Substr ($url,0,5)==' https ') {curl_setopt ($ch, Curlopt_ssl_verifypeer,false);//Skip certificate Checkcurl_setopt ($ch, Curlopt_ssl_verifyhost,true);//Check whether the SSL encryption algorithm exists from the certificate} curl_setopt ($ch, Curlopt_returntransfer,true); curl_setopt ($ch, Curlopt_url,$url); curl_setopt ($ch, Curlopt_httpheader,$header); curl_setopt ($ch, Curlopt_post,true); curl_setopt ($ch, Curlopt_postfields, Http_build_query ($content));$response= Curl_exec ($ch);if($error=curl_error ($ch)){ die($error); } curl_close ($ch);return$response;}?>

Receive Header

We can get header data in $_server, and the custom data is prefixed with HTTP_, so we can read the data of the HTTP_ prefix.

    $post _data=$_post;$header= Get_all_headers ();$ret=Array();$ret[' Post '] =$post _data;$ret[' Header '] =$header; Header (' Content-type:application/json;charset=utf8 ');EchoJson_encode ($ret, json_unescaped_unicode| Json_pretty_print);/** * Getting custom Header data * / functionget_all_headers(){//Ignore fetched header data$ignore=Array(' Host ',' Accept ',' Content-length ',' Content-type ');$headers=Array();foreach($_server as$key=$value){if(Substr ($key,0,5)===' Http_ '){$key= substr ($key,5);$key= Str_replace ('_',' ',$key);$key= Str_replace (' ','-',$key);$key= Strtolower ($key);if(!in_array ($key,$ignore)){$headers[$key] =$value; }        }    }return$headers;}?>

Output:

POST data:Array(    [name] => fdipzone)Header data:Array(    [token] => JxRaZezavm3HXM3d9pWnYiqqQC1SJbsU    [language] => zh    [region] => GZ)

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above introduces PHP through the header to send custom data, including aspects of the content, I hope to be interested in PHP tutorial friends helpful.
