Kazi get_declared_interfaces

Kazi get_declared_interfaces hurudisha safu ya majina ya interfaces zote, ambazo zimetangazwa katika hati ya sasa au zimepakizwa kupitia upakiaji otomatiki. Kazi haikubali vigezo.

Mtindo

get_declared_interfaces();

Mfano

Wacha tupate orodha ya interfaces zote zilizotangazwa:

<?php
	interface MyInterface1 {}
	interface MyInterface2 {}
	
	$res = get_declared_interfaces();
	print_r($res);
?>

Matokeo ya utekelezaji wa kodi:

[..., 'MyInterface1', 'MyInterface2']

Mfano

Wacha tuangalie ikiwa orodha ina interface maalum:

<?php
	interface LoggerInterface {}
	
	$interfaces = get_declared_interfaces();
	$res = in_array('LoggerInterface', $interfaces);
	var_dump($res);
?>

Matokeo ya utekelezaji wa kodi:

true

Mfano

Wacha tulinganishe orodha ya interfaces kabla na baada ya kutangaza interface mpya:

<?php
	$before = get_declared_interfaces();
	interface NewInterface {}
	$after = get_declared_interfaces();
	
	$res = array_diff($after, $before);
	print_r($res);
?>

Matokeo ya utekelezaji wa kodi:

['NewInterface']
