Kubainisha Fumbo Muhula katika PHP

Ikiwa ni lazima, muhula unaweza kubainishwa waziwazi:

php<?php
  $arr = []; // tunaunda safu tupu
  
  $arr[0] = 'a'; // kwenye muhula 0 tunaongeza kipengele 'a'
  $arr[1] = 'b'; // kwenye muhula 1 tunaongeza kipengele 'b'
  $arr[2] = 'c'; // kwenye muhula 2 tunaongeza kipengele 'c'
  
  var_dump($arr); // itatoa ['a', 'b', 'c']
?>

Muhula inaweza kuwa sio tu nambari, bali pia ya maneno:

php<?php
  $arr = [];
  
  $arr['a'] = 1;
  $arr['b'] = 2;
  $arr['c'] = 3;
  
  var_dump($arr); // itatoa ['a' => 1, 'b' => 2, 'c' => 3]
?>

php<?php
  $arr = [];
?>
