The best way I've found is to do something like this:
if(isset($_POST['submit']))
{}
Note that in-place of submit you can put the name of any form element. I
chose submit here, because every form should have a submit button. Note
also that this will only work if you have given your submit button a
name:
<input type="submit" name="submit" value="Submit"/>
