php
ReflectionMethod ReflectionMethod::getPrototype( void )Parameters: This function does not accept any parameter. Return Value: This function returns the prototype of the specified method otherwise, an exception/error is returned if the method does not have a prototype. 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:
Program 2:
object(ReflectionMethod)#2 (2) {
["name"]=>
string(13) "Marketing_Dpt"
["class"]=>
string(11) "Department1"
}
<?php
// Initializing a user-defined class
class Company {
protected function GeeksforGeeks($name) {
return 'GFG' . $name;
}
}
// Using ReflectionMethod() over the class Company
$A = new ReflectionMethod('Company', 'GeeksforGeeks');
// 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.
