I am absolutely sure of thus since I cut and pasted the original problem code to a shell script to test. This was before I noticed the answer mentioning the closing if block had already been posted. > > So what do you think this will output? > > $a = "123\n"; > $a++; > echo $a; > > Try it. Undoubtedly the above will work as we both know, the output will be "123"; however, if you look at the original code in question, there is no "\n" tailing the output written to the counter file and thus the increment works fine (unless of course when he created the file to begin he had a newline - something I did not do in my test :) Cheers, Rob. -- .---------------------------------------------. | Worlds of Carnage - http://www.wocmud.org | :---------------------------------------------: | Come visit a world of myth and legend where | | fantastical creatures come to life and the | | stuff of nightmares grasp for your soul. | `---------------------------------------------' -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
