Kujaza Arrays Nyingi za PHP

Hebu sasa tuchague kutumia kitanzi kuunda aina yoyote ya array nyingi na nambari.

Kwa mfano, hii array ya pande mbili:

php<?php
  [[1, 2, 3], [1, 2, 3], [1, 2, 3]]
?>

Wacha tusuluhishe kazi iliyowekwa, kwa kutumia vitanzi viwili vilivyowekwa ndani. Kitanzi kikuu kitaunda arrays ndogo, na kile kilichowekwa ndani - kujaza arrays hizi ndogo kwa nambari:

php<?php
  $arr = [];
  
  for ($i = 0; $i < 3; $i++) {
    for ($j = 0; $j < 3; $j++) {
      $arr[$i][$j] = $j + 1; // kujaza array ndogo kwa nambari
    }
  }
  
  var_dump($arr);
?>

javascript[[1, 2, 3, 4, 5], [1, 2, 3, 4, 5], [1, 2, 3, 4, 5]]

javascript[['x', 'x', 'x', 'x'], ['x', 'x', 'x', 'x'], ['x', 'x', 'x', 'x']]

javascript[
  [
    [1, 2, 3, 4, 5],
    [1, 2, 3, 4, 5],
  ],
  [
    [1, 2, 3, 4, 5],
    [1, 2, 3, 4, 5],
  ],
  [
    [1, 2, 3, 4, 5],
    [1, 2, 3, 4, 5],
  ],
]
