// Getting the ReflectionClassConstant
print_r($a);
?>
输出:
ReflectionClassConstant Object ( [name] => First [class] => Company )
示例2:
<?php
// Declaring a user-defined class Departments
class Departments {
// Defining some constants
const D1 = "EE";
const D2 = "Civil";
const D3 = "CSE";
const D4 = "IT";
}
// Using the ReflectionClass() function
// over the Departments class
$A = new ReflectionClass('Departments');
// Calling the getReflectionConstant() function
// over specified constants
$a1 = $A->getReflectionConstant('D1');
$a2 = $A->getReflectionConstant('D2');
$a3 = $A->getReflectionConstant('D3');
$a4 = $A->getReflectionConstant('D4');
// Getting the ReflectionClassConstant
print_r($a1);
print_r($a2);
print_r($a3);
print_r($a4);
?>
输出:
ReflectionClassConstant Object ( [name] => D1 [class] => Departments ) ReflectionClassConstant Object ( [name] => D2 [class] => Departments ) ReflectionClassConstant Object ( [name] => D3 [class] => Departments ) ReflectionClassConstant Object ( [name] => D4 [class] => Departments )
