返回值：此函數返回指定方法的數組。

以下示例程序旨在說明PHP中的ReflectionClass::getMethods()函數：

示例1:

<?php 
  
// Initialising a user-defined Class 
class Departments { 
    public function CSE() { } 
    final protected function ECE() { } 
    private static function EE() { } 
    static function IT() { } 
    private function Mechnical() { } 
} 
  
// Using ReflectionClass() over the 
// user-defined class Departments 
$class = new ReflectionClass('Departments'); 
  
// Calling the getMethods() function 
$methods = $class->getMethods(); 
  
// Getting an array of specified methods 
var_dump($methods); 
?>

輸出：

array(5) {
  [0]=>
  object(ReflectionMethod)#2 (2) {
    ["name"]=>
    string(3) "CSE"
    ["class"]=>
    string(11) "Departments"
  }
  [1]=>
  object(ReflectionMethod)#3 (2) {
    ["name"]=>
    string(3) "ECE"
    ["class"]=>
    string(11) "Departments"
  }
  [2]=>
  object(ReflectionMethod)#4 (2) {
    ["name"]=>
    string(2) "EE"
    ["class"]=>
    string(11) "Departments"
  }
  [3]=>
  object(ReflectionMethod)#5 (2) {
    ["name"]=>
    string(2) "IT"
    ["class"]=>
    string(11) "Departments"
  }
  [4]=>
  object(ReflectionMethod)#6 (2) {
    ["name"]=>
    string(9) "Mechnical"
    ["class"]=>
    string(11) "Departments"
  }
}

示例2:

<?php 
  
// Initialising a user-defined Class 
class Departments { 
    public function CSE() { } 
    final protected function ECE() { } 
    private static function EE() { } 
    static function IT() { } 
    private function Mechnical() { } 
} 
  
// Using ReflectionClass() over the 
// user-defined class Departments 
$class = new ReflectionClass('Departments'); 
  
// Calling the getMethods() function 
$methods = $class->getMethods(ReflectionMethod::IS_STATIC); 
  
// Getting an array of specified methods 
var_dump($methods); 
?>

輸出：

array(2) {
  [0]=>
  object(ReflectionMethod)#2 (2) {
    ["name"]=>
    string(2) "EE"
    ["class"]=>
    string(11) "Departments"
  }
  [1]=>
  object(ReflectionMethod)#3 (2) {
    ["name"]=>
    string(2) "IT"
    ["class"]=>
    string(11) "Departments"
  }
}
