It's not a question of Me determining that.  If the original function 
returned "false" then the try should catch it and in your 'catch' block 
you can display a message and show the php error.  In the case where you 
expect a 'false' return, then just reverse your try condition, and 
display the appropriate message (without a php error messsage).  Or even 
simpler, just use an If statement.
