Kuingiza Faili katika PHP

Hebu tuchukue kuwa tuna faili moja:

index.php<?php
  echo 'index';
?>

Hebu pia tuwe na faili ya pili:

test.php<?php
  echo 'test';
?>

Hebu tuingize yaliyomo kwenye faili ya pili ndani ya ya kwanza. Hii inafanywa kwa kutumia kiopereta include:

index.php<?php
  include 'test.php';
  echo 'index';
?>

Faili moja ile ile inaweza kuingizwa mara nyingi kadiri unavyotaka:

index.php<?php
  include 'test.php';
  include 'test.php';
  include 'test.php';
  
  echo 'index';
?>
