The ReflectionClass::getMethods() function is an inbuilt function in PHP which is used to return an array of specified methods.
Syntax:

array ReflectionClass::getMethods( int $filter )

Parameters: This function accepts a single parameter filter which is used to remove some of the methods.
Return Value: This function returns an array of specified methods.
Below programs illustrate the ReflectionClass::getMethods() function in PHP:
Program 1:

    final protected function ECE() { }
    private static function EE() { }
    static function IT() { }
    private function Mechanical() { }
}

// Using ReflectionClass() over the
// user-defined class Departments
$class = new ReflectionClass('Departments');

// Calling the getMethods() function
$methods = $class-&gt;getMethods();

// Getting an array of specified methods
var_dump($methods);
?&gt;

&lt;?php
