Arrays in PHP

I was reading over the PHP Documentation for Arrays and i so use to making arrays the way I learned them...

PHP:

$cash = ("I have lot of"," cash in my pocket");


But while reading over the docs , I see a whole new syntax look!

PHP:

<?php
$array = array(
    "foo" => "bar",
    42    => 24,
    "multi" => array(
         "dimensional" => array(
             "array" => "foo"
         )
    )
);

var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>


As You can see I don't understand thios at all!! What I think it means is

PHP:

<?php
$array = array( //starg of the array
    "foo" => "bar", // [0] replacement
    42    => 24, // replecing [1]
    "multi" => array( // Fucking lost!
         "dimensional" => array(
             "array" => "foo"
         )
    )
);

var_dump($array["foo"]); // will display variables in "foo" array section ?
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>


Halp Meh? <3

As a config it would be:

Code:

foo: bar
42: 24
multi:
   dimensional:
      array: foo

Maybe that helps

what?

PHP arrays are actually like maps in Java. The keys can be string and/or int. "foo" => "bar" is equivalent to a map entry with String key foo and String value bar.

If strings and ints are used together as keys, ints will be casted into strings.
