No, you don't _have_ to start using PHP 5. You can wait til eternity for someone to actually fix this in PHP 4. :) (I just wanted to know that this only happens with PHP 4) Yet another reason to update. Previous Comments: ------------------------------------------------------------------------ [2005-09-30 20:54:36] dcpiper at indiana dot edu Yep, with the PHP5 snapshot it works fine. Do I have to upgrade everything to PHP5? The value is set correctly and maintained. I get this now: /usr/src/apbuild/php5-200509301830/sapi/cli/php signaltest.php Setting signal handlers ... Done Generating signal to self... Got signal 15 in SignalHandler: object(SigTest)#1 (2) { ["myvalue"]=> int(15) ["something"]=> string(52) "This data was set after the handler was instantiated" } Main execution, looking at $jm object: object(SigTest)#1 (2) { ["myvalue"]=> int(15) ["something"]=> string(52) "This data was set after the handler was instantiated" } ------------------------------------------------------------------------ [2005-09-27 19:09:19] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ [2005-09-26 21:23:09] dcpiper at indiana dot edu Description: ------------ I have noticed that even though a class function can be registered as a callback, it is not possible to set/update a class variable from within the signal handler and get it to be set within the actual 'live' instance of that object. Is this a bug? It seems cumbersome to have to resort to global variables in order to actually DO something with the signal other than print out strings saying 'I got one!' Reproduce code: --------------- class SigTest { var $myvalue; function SignalHandler($signo) { echo "Got signal $signo \n"; $this->myvalue = $signo; echo "in SignalHandler:\n"; var_dump($this); } function SigTest() { declare (ticks = 1); $this->myvalue = 'some initial state'; echo "Setting signal handlers ... "; pcntl_signal(SIGTERM, array(&$this, 'SignalHandler')); pcntl_signal(SIGINT, array(&$this, 'SignalHandler')); pcntl_signal(SIGHUP, array(&$this, 'SignalHandler')); $this->something = 'This data was set after the handler was instantiated'; echo "Done\n"; } } $jm = new SigTest; sleep(2); echo "Generating signal to self...\n"; posix_kill(posix_getpid(), SIGTERM); echo "Main execution, looking at \$jm object:\n"; var_dump($jm); Expected result: ---------------- Expected that 'myvalue' class variable change from within signal handler was visible outside of that function, i.e. a change made, not reverted to the state it was in previously before the signal was handled. Actual result: -------------- Setting signal handlers ... Done Generating signal to self... Got signal 15 in SignalHandler: object(sigtest)(2) { ["myvalue"]=> int(15) ["something"]=> string(52) "This data was set after the handler was instantiated" } Main execution, looking at $jm object: object(sigtest)(2) { ["myvalue"]=> string(18) "some initial state" ["something"]=> string(52) "This data was set after the handler was instantiated" } Last 'var_dump' SHOULD be the same as the first one, in my opinion. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34650&edit=1
