Maybe you guys should take a read about pre- and post-increment :-) Sam Masiello wrote: This drove me nuts for a while and instead of doing $variable++ I started using ++$variable and never had the problem again. --Sam Jake McHenry wrote: No. $correct++; Is all you need for the second conditio

Re: [PHP] Simple: Whats wrong with this?

Not that I'm aware of. In every incantation I've ever seen of the incrementing, $correct++; Is always, 100% equal to: $correct = ($correct + 1); But, maybe you ran into a case where it's not, you never know. On Wed, 2004-03-17 at 12:00, Jake McHenry wrote: > > No. > > > > $correct++; > > > > I

No. $correct++; Is all you need for the second condition, it automatically sets itself back. On Wed, 2004-03-17 at 11:52, Shane McBride wrote: > I have a form variable I want to increment by a value of 1 each time the > page loads. Here's what I have so far: > > if(!isset($correct)) { >

[PHP] Simple: Whats wrong with this?

I have a form variable I want to increment by a value of 1 each time the page loads. Here's what I have so far: if(!isset($correct)) { $correct = 0; } else { $correct = $correct++; } Seems like it should work? Thanks! Shane -- PHP General Mailing List (http://ww
