[SOLVED] Variable arrays without an array

[Xeoncross]

If the title is confusing you might want to take a look at this:

 

<?php
function random_charaters($number) {
    $ANC = 'ACEFGHJKLMNPRSTUVWXY345679';
    $chars = null;
    for($i=0; $i<$number; $i++) {
        $chars .= $ANC{rand(0,26)}; //<-- Take a look at this 
    }
    return $chars;
}
//returns something like: A3GMN99
?>

 

Now when I use this function PHP throws a E_NOTICE error. The function works fine - but I don't like to go against PHP. 

 

So that brings me to the topic of how should I properly use "variable arrays"? (or whatever you call them: Variable Variables)

Theres not really such a thing as variable arrays and your not using variable variables. Your simply trying to access indexes of a string.

 

What version of php are you using?

 

Use [] instead. eg;

 

$chars .= $ANC[rand(0,26)];

It should throw a random 'Uninitialized string offset' error. The max value in the rand() function is larger than the amount of values in the $ANC array. It should be 25.

Sorry, I should say...

 

Your simply trying to access string elements via an index.

Now I know I need to go to bed...   thanks Daukan.
