Re: exit in class constructor crashes

Last week ended with this quagmire of not being able to exit before the end of a class' constructor function. Very frustrating. So I was glad to go visit my sweet heart. While we were hanging out, I had a flash of inspiration. The next day, we were passing the time telling stories. Figured, if she's going to make a story teller out of me, I'll make a programmer out of her. She was amenable. So, today, she sits down at the controls, with I in the navigator's seat. We stripped everything out of the class to make the experiment simple. The test had a class and a constructor function. The function says hello and then tries to exit(). As expected, BLAMO! PHP crashes. Okay, now for the bright idea... I explain the purposes of brackets and nesting. Then, at the point in the class where the exit() is supposed to happen, we substitute an include file. This include contains a "}" and the exit() in order to fake the function into thinking it reached the end of the function, THEN calling the exit(). Okay, now the moment of truth... Flip over to the web browser, hit the refresh button.... "YES!" I exclaim and then jump out of my seat, jump up and down shouting "I am master of the universe!" Okay, at least MY universe :) None the less, this trick works! :) Here's the test. It's broken up into two files, test.htm and fake.inc. -------------------------------------------------------------- test.htm ---------------------- <?php class ConstructorExit { function ConstructorExit() { echo "Welcome to the Constructor Exit Test."; # exit(); # But, if you exit here, PHP crashes. # So, include this fakeout... include ("./fake.inc"); }# End of function ConstructorExit }# End of class ConstructorExit $Post = new ConstructorExit; ?> ----------------------- fake.inc ----------------------- <?php }# End of function ConstructorExit echo "<br>Well, you're now out of the function."; echo "<br>Now, try exiting."; exit(); echo "If you see this, the program didn't exit."; ?> ---------------------------------------------------------- Guess the only question is "will it work in PHP 4?" Hmm, maybe another question is, is this workaround not needed in PHP 4 because one can exit() from constructors? Well, hope you like the fix and the story. Enjoy, --Dan PS: Jen, your inspiration and support go a long way. Thanks! -- T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y More than just answers. Solutions.
