[SOLVED] Basic array key question

[php_joe]

Do leading zeros matter in array keys?

 

is $var[04] the same as $var[4]?

[hitman6003]

They shouldn't matter unless they are passed as a string...e.g. :

 

$var['04'] != $var[04]

Even if numeric they are not the same.

 

<?php
$a = array();

$a[010] = 'Hello';
$a[10] = 'World';

echo '<pre>', print_r($a, true), '</pre>';

?>

-->

Array
(
    [8] => Hello              // 010 is octal for 8
    [10] => World
)


[/pre}

Even if numeric they are not the same.

 

Hmm... in that case is there a function that strips leading zeros off of numbers?

[Barand]

intval()

[php_joe]

intval()

 

Thank you
