multi dimensional arrays [resolved]

I know this might seem easy, but I have been looking and either can't find what I'm looking for or I find something that looks very complex.

Firstly how do you define an array, I PHP is typeless, but in JavaScript I always define arrays out of habit, and I would like to keep up the habit.

secondly, how do you make a multiD one?

I thought it would be:
$a = new array();
//or new array($a);
then:
$a[0] = ["1","2"];
$a[1] = ["3","4"];
etc.

I get errors though.
Someone please help.

Look this over..

PHP Code:

---

<?
  //declare the array
  $arr = array();
  //declare some arrays inside of that array if you want..
  $arr[0] = array();
  $arr[1] = array();
  //add some values to the arrays
  $arr[0][0] = 'one';
  $arr[0][1] = 'two';
  $arr[1][0] = 'three';
  $arr[1][1] = 'four';
  //print out the arrays
  $br = "\n";
  echo '<pre>';
  for($i = 0; $i < count($arr); $i++){
    echo '$arr[' . $i . '] {' . $br;
    for($j = 0; $j < count($arr[$i]); $j++){
      echo '  $arr[' . $i . '][' . $j . '] = ' . $arr[$i][$j] . $br;
    }
    echo '}'  . $br . $br;
  }
  echo '</pre>';
?>

Hope that helps you out a bit.

It makes sense actually. I don't like having to make each sub thing another array, but it makes sense, thx.

Another method is:

PHP Code:

---

<?php
  //declare the array 
  $arr = array(); 

  //declare some arrays inside of that array if you want.. 
  $arr[0] = array('one', 'two'); 
  $arr[1] = array('three', 'four'); 
?>

---

Or:

PHP Code:

---

<?php
  //declare the array 
  $arr = array(array('one', 'two'), array('three', 'four')); 
?>
