范例

示例 #1 forward_static_call() example

<?php

class A
{
    const 
NAME 'A';
    public static function 
test() {
        
$args func_get_args();
        echo static::
NAME" ".join(','$args)." \n";
    }
}

class 
extends A
{
    const 
NAME 'B';

    public static function 
test() {
        echo 
self::NAME"\n";
        
forward_static_call(array('A''test'), 'more''args');
        
forward_static_call'test''other''args');
    }
}

B::test('foo');

function 
test() {
        
$args func_get_args();
        echo 
"C ".join(','$args)." \n";
    }

?>

以上例程會輸出:

B
B more,args 
C other,args
