min() function stops on arrays...

Hi there
In my script I gather some integers into a array called $patpos. Then I
search for the lowest integer in that array : $patpos = min($patpos);
And I'm supposed to have the lowest value in the $patpos (I know it's not an
array anymore) - but this does work only if there's one element in the
array. When I have two or more - the script stops without any notice - this
started after I upgraded to PHP 4.0.0
Please help or gimme an alternative - I have a search engine based on this
:-)
