[TYPO3] Using my_inventory extension when php version < 5

[Jason Steiner]

I found the extension, my_inventory, in the repository today and it 
seemed pretty useful. I installed it even though I didn't have any 
immediate need for it.

One problem I encountered though, upon using the extension on my server 
which has a PHP version < 5, I received an error saying that the 
function, stripos is undefined. It's not available in versions of PHP 
less than 5.

So searching, I found the solution posted here:
http://www.php.net/manual/en/function.stripos.php#63370

Just copy the following code and put it in the file 
class.tx_myinventory_pi1.php and it will work just fine

function stripos($str,$needle) {
    return strpos(strtolower($str),strtolower($needle));
   }

I just pasted the above code right above the call to the stripos function.
