Is this a bug in PHP? [duplicate]

Answer 1

08 is treated as octal.

Don't use leading zeros.

For that matter, don't use explicit indices for creating arrays:

$fruit = array(
           "Apples",
           "Pears",
           etc
         );

(or for PHP 5.4 and newer):

$fruit = [
           "Apples",
           "Pears",
           etc
         ];

Answer 2

Because you typed 08 rather than 8 PHP thinks you are talking about a value that doesn't exist. In octal numbers run from 00 to 07. To let PHP take care of the values for you type:

<pre>
<?php

$fruit[] = "Apples";
$fruit[] = "Pears";
$fruit[] = "Bananas";
$fruit[] = "Grape";
$fruit[] = "Orange";
$fruit[] = "Peach";
$fruit[] = "Lemon";
$fruit[] = "Cherry";
$fruit[] = "Mango";

print_r($fruit);

?>
</pre>

In short it's not a bug but it is one of those things that will catch you out if you were not expecting it.
