Re: Checking for empty()

I have a form with various fields on it that I want to make sure aren't empty or the user didn't just hit the space bar or return (in a text field). What's the best way to do this? Seems empty() will fail on a textarea if the user simply hits a space or return and submits the form.

if (strlen(trim($var)) == 0)

    print "It's empty";
