PHP sends custom data methods via header

The following small series for you to share a PHP through the header to send a custom data method, with a good reference and learn the value of PHP, we hope to help. Interested in PHP to follow the small part of it come to see it

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

Send header:

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

<?php$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 ( $response, True); Echo ' Post data: ' Echo ' <pre> ';p rint_r ($data [' POST ']); Echo ' </pre> '; Echo ' Header data: '; Echo ' <pre> ';p rint_r ($data [' Header ']), echo ' </pre> ';/** * Send data * @param String $url The requested address * @param Array $he Ader Custom Header Data * @param Array $content Post data * @return String */function tocurl ($url, $header, $content) {$ch = Curl  _init (); if (substr ($url, 0,5) = = ' https ') {curl_setopt ($ch, Curlopt_ssl_verifypeer, false);//Skip certificate Check curl_setopt ($ch, curlopt_s Sl_verifyhost, True);  Check the existence of the SSL encryption algorithm from the certificate} curl_setopt ($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.

<?php$post_data = $_post; $header = Get_all_headers (); $ret = Array (); $ret [' post '] = $post _data; $ret [' header '] = $ Header;header (' Content-type:application/json;charset=utf8 '); Echo Json_encode ($ret, json_unescaped_unicode| Json_pretty_print)/** * Gets the custom header data */function get_all_headers () {  //ignores the header data obtained  $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] = en  [Region] = GZ)
