我的spl_autoload_register（）函数不适用于cpanel，但在localhost中工作正常

Question

My spl_autoload_register() function is not working for cpanel but working fine in localhost.

Here is the code for input class in input.php file:-

class Input {
public static function exists($type = 'post') {
    switch($type) {
        case 'post':
            return return $_POST[$item];
            break;
        default:
            return false;
        break;
    }
}}

and through this init.php file below I am trying to access my input.php file.

spl_autoload_register(function($class) {
   require_once $class . '.php';
});

and now I am trying to get access the init.php file in my form.php file and I am unable to view the page and it is showing me the blank screen while uploading these files in cpanel but in my local host it is ok.

 require_once 'init.php';

 if(Input::exists()) {
   <form action="" method="post">
        <label for='name'>name</label>
        <input type="text" name="name" id="name">
    <input type="submit" value="Login">
   </form>
   }else{
       echo "no form";
   }
