[thelist] [PHP] variable conversion tip

[Paul Bennett]

<tip type="PHP and string->number conversion">
Having trouble getting PHP to treat string data (POST or GET) as a 
number for a script calculation?

Multiply the data you are using in calculation by 1 and then use it - 
this seems to tell PHP to treat the data as numeric

# sample code
$duration_in_seconds = ($HTTP_POST_VARS['p_duration'] * 1) * 60;

:)
