PHP Development API Interface code sharing

This article is mainly to share with youPhp Implementing the API interface code, to realize the user's registration, login, query user information function, is to learn PHP API development of good examples, hope to help everyone.

the service-side portion of the PHP API interface

code example:

<?php/*** Three mesh * PHP Development API Interface Server */require ' conn.php ';  Header (' Content-type:text/html;charset=utf-8 '); $action = $_get[' action '];         Switch ($action) {//Registered member case "Adduserinfo";         $username = Lib_replace_end_tag (Trim ($_get[' username '));         $password 2 = Lib_replace_end_tag (Trim ($_get[' userpassword ')); $password = MD5 ("$password 2".         ALL_PS);          $email = Lib_replace_end_tag (Trim ($_get[' email '));             if ($username = = "| | $password 2 = =" ' | | $password = = ') {$res = UrlEncode ("wrong parameter"); Exit (Json_encode ($res));         Free information} $sql = "Select username from ' member ' where username= ' $username '";         $query = mysql-query.html Target=_blank class=infotextkey>mysql_query ($sql, $conn);          $count = mysql_num_rows ($query); if ($count > 0) {exit (Json_encode (1));//return 1 means registration failed} else {$addsql = "insert INTO ' m Ember ' (Username,password,email) VALUES (' $username ', ' $password ',' $email ') ";             mysql_query ($addsql); Exit (Json_encode (0));       Returns 0 for registration success} break;         Query user Information case "Selectuserinfo";         $username = Lib_replace_end_tag ($_get[' username ');         $sql = "Select Id,username,nickname,mobile from ' member ' where username= ' $username '";         $query = mysql_query ($sql, $conn);         $row = Mysql_fetch_array ($query);         foreach ($row as $key = = $v) {$res [$key] = UrlEncode ($v);         } exit (Json_encode ($res));    Break         Member Login Case "Userlogin";         $username = Lib_replace_end_tag ($_get[' username ');         $password 2 = Lib_replace_end_tag (Trim ($_get[' userpassword ')); $password = MD5 ("$password 2".

PHP API Client Section

code example:

<?php/*** PHP API Interface Client * EDIT: Office supplies */header (' content-type:text/html;charset=utf-8 ');     Avoid output garbled function HttpPost ($url, $parms) {$url = $url. $parms;     if ($ch = Curl_init ($url)) = = False) {throw new Exception (sprintf () ("Curl_init error for URL%s.", $url));     } curl_setopt ($ch, Curlopt_returntransfer, 1);     curl_setopt ($ch, Curlopt_header, 0);     curl_setopt ($ch, Curlopt_connecttimeout, 600);     curl_setopt ($ch, curlopt_followlocation, 1);     if (Is_array ($parms)) {curl_setopt ($ch, Curlopt_httpheader, Array (' Content-type:multipart/form-data; '));     } $postResult = @curl_exec ($ch);     $http _code = Curl_getinfo ($ch, Curlinfo_http_code);         if ($postResult = = = False | | $http _code! = | | | Curl_errno ($ch)) {$error = Curl_error ($ch);         Curl_close ($ch);     throw new Exception ("HTTP POST FAILED: $error");         } else {//$postResult =str_replace () ("\XEF\XBB\XBF", "', $postResult); Switch (Curl_getinfo ($ch, CURLinfo_content_type) {case ' Application/json ': $postResult = Json_decode () ($postResult);         Break         } curl_close ($ch);     return $postResult;  }} $postUrl = "http://pujia.test.com/api/server.php"; $p =$_get[' P '];     if ($p = = "Selectuserinfo") {$username = $_get[' username ']; $parms = "?
