Mtindo

phpget_declared_interfaces();

Mfano

Wacha tupate orodha ya interfaces zote zilizotangazwa:

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

Matokeo ya utekelezaji wa kodi:

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

Mfano

Wacha tuangalie ikiwa orodha ina interface maalum:

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

Matokeo ya utekelezaji wa kodi:

phptrue

Mfano

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

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

Matokeo ya utekelezaji wa kodi:

php['NewInterface']
