How to use PHP Objects globally, and include objects from multiple file inside a function of a class? -

-

assume, have 2 files:

dbconnect.php calculate.php

  • calculate has abstract class "authx" functions login, signup, forgotpass, newsdisplay etc.

  • to make functions work hav actual class "auth" above functions added in class file.

  • db connect.php has database related functionalities, has class file

  • now, need use objects of dbcon inside login, signup, forgotpass.etc., 1 way include settings in each of these functions again , again, works fine.

but alternative , better solution think assigning , using database objects great inside functions better code flow.

dbcon.php

<?php class dbcon{     function connect(){         $servername = "localhost";         $username = "root";         $password = "";         $dbname="work_steelnext";         // create connection         $conn = new mysqli($servername, $username, $password,$dbname);     // check connection     if ($conn->connect_error) {         die("connection failed: " . $conn->connect_error);     }     else{         echo "connected successfully";     }     }     function disconnect(){         mysqli_close($conn);     } }    ?>

calculate.php

<?php include 'dbcon.php'; /** * make use of json standard thing! *do error handling totally *make login, noback, signup, forgot password, deploy on server,  **/ /** * connecting database **/  abstract class auth {     /**     *setting abstract classes login file     *     **/      abstract function login();     /**      *developing sign module     *     **/     abstract function signup();     /**     *forgot pass     **/     abstract function forgotpass(); } /** *this class make login work **/  /** *make json based switch */  class authx extends auth {      function jsonhandler(){         //data switch information     }     function login()     {     }     function signup()     {     // $test = new authx();     // echo $test->forgotpass();     //wrong way code      //$getname="chocolate";     $get_uname=$_get['signupname'];     $get_uemail=$_get['signupemail'];     $get_upwd=$_get['signuppwd'];      //$get_uemail=$_get['uemail'];     echo "variable  ".$getname. "<br/>";     //$sql = "insert `tb_users`(`u_id`, `u_name`, `u_email`, `u_pwd`) values (null,\"hello\",\"hello\",\"hey\")";     //$sql="insert names(name,email) values('$get_uname','$get_uemail')";     $sql="insert tb_users(u_id,u_name,u_email,u_pwd) values(null,'$get_uname','$get_uemail','$get_upwd')";      $dblink=new dbcon();     echo $dblink->connect();     $conn="x";     if (mysqli_query($conn, $   sql)) {         echo "new record created successfully";         echo $get_uname."stored".$get_uemail;     } else {         echo "error: " . $sql . "<br>" . mysqli_error($conn);     }     mysqli_close($conn);     }      function forgotpass()     {     }      function switchandle($a)     {         switch($a)         {             case 'login':             echo "\nlogin entered";             break;             case 'signup':             echo "\nsigningup entered";             break;             case 'forgot':             echo "\ni forgot password";             break;             default :             echo "\nnull";             break;         }     } }  $test = new authx(); // echo $test->switchandle("login"); echo $test->signup(); ?>

i recommend following standard structuring code , using autoloading. check out link: http://www.sitepoint.com/autoloading-and-the-psr-0-standard/.
