// Initialising a class of Interfaces 
class Interfaces implements Colleges, Departments, Students, Companies { } 
  
// Using ReflectionClass over the class Interfaces 
$A = new ReflectionClass("Interfaces"); 
  
// Calling the getInterfaces() function 
$B = $A->getInterfaces(); 
  
// Getting the associative array of interfaces 
print_r($B); 
?>

輸出:

Array
(
    [Colleges] => ReflectionClass Object
        (
            [name] => Colleges
        )

    [Departments] => ReflectionClass Object
        (
            [name] => Departments
        )

    [Students] => ReflectionClass Object
        (

示例2:

<?php 
   
// Using ReflectionClass  
$ReflectionClass = new ReflectionClass('ReflectionClass'); 
   
// Calling getInterfaces() functions 
$A = $ReflectionClass->getInterfaces(); 
   
// Getting the associative array of interfaces 
var_dump($A); 
?>

輸出:

array(1) {
  ["Reflector"]=>
  object(ReflectionClass)#2 (1) {
    ["name"]=>
    string(9) "Reflector"
  }
