PHP implementation method for registering, logging in, and querying the API interface of user data function

This article mainly introduces the PHP implementation of registration, login and query user Data API interface, combined with specific examples of PHP server-side user registration, login, query and Curl Landing query function implementation skills, the need for friends can refer to the next

Specific as follows:

Service side

<?phprequire ' 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 '";    $query = mysql_query ($sql, $conn);    $count = mysql_num_rows ($query); if ($count > 0) {exit (Json_encode (1));//return 1 means registration failed} else {$addsql = "insert INTO ' member ' (Username,pas      Sword,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".    ALL_PS); $sqluser = "Select Id,username,password from ' member ' where Username= '". $username. "' and password= '". $password.    "'";    $queryuser = mysql_query ($sqluser);    $rowuser = Mysql_fetch_array ($queryuser); if ($rowuser && is_array ($rowuser) &&!empty ($rowuser)) {if ($rowuser [' username '] = = $username & & $rowuser [' password '] = = $password) {if ($rowuser [' password '] = = $password) {$res = UrlEncode ("Login Successful          ");        Exit (Json_encode ($res)); } else {$res =UrlEncode ("Password error");        Exit (Json_encode ($res));        }} else {$res = UrlEncode ("User name does not exist");      Exit (Json_encode ($res));      }} else {$res = UrlEncode ("User name password error");    Exit (Json_encode ($res));  }/* * 0: Indicates successful login, 1: Password error, 2: User name does not exist, 3: User name password error */break; Default:exit (Json_encode (Error));}? >

Client Example:

<?phpheader (' 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 ': $postResult = Json_decode ($postRe        Sult); Break;    } curl_close ($ch);  return $postResult; }} $postUrl = "http://pujia.test.com/api/server.php"; $p =$_get[' P '];if ($p = = "Selectuserinfo") {$username = $_get['  Username ']; $parms = "?
