Below programs illustrate the ReflectionMethod::getPrototype() function in PHP:
Program 1:
<?php // Initializing a user-defined class Department1 class Department1 { public function Marketing_Dpt() { return 'Department1'; } } // Initializing a subclass of the above class Department1 class Department2 extends Department1{ public function Marketing_Dpt() { return 'Department2'; } } // Again Initializing a subclass of the above subclass Department2 class Department3 extends Department2{ public function Coding_Dpt() { return 'Department3'; } } // Using the ReflectionMethod() over the above // subclass Department2 $A = new ReflectionMethod('Department3', 'Marketing_Dpt'); // Calling the getPrototype() function $B = $A->getPrototype(); // Getting the prototype var_dump($B); ?> |
Output:
object(ReflectionMethod)#2 (2) {
["name"]=>
string(13) "Marketing_Dpt"
["class"]=>
string(11) "Department1"
}
Program 2:
<?php // Initializing a user-defined class class Company { protected function neveropen($name) { return 'GFG' . $name; } } // Using ReflectionMethod() over the class Company $A = new ReflectionMethod('Company', 'neveropen'); // Calling the getPrototype() function $B = $A->getPrototype(); // Getting the prototype or an error is returned // if the method does not have a prototype. var_dump($B); ?> |
Output: Method does not have any prototype that will give you an error.
