Edit report at https://bugs.php.net/bug.php?id=72409&edit=1 ID: 72409 Comment by: dave at mudsite dot com Reported by: jan dot kahoun at heureka dot cz Summary: pcntl_signal function could return previous value of the signal handler Status: Open Type: Feature/Change Request Package: PCNTL related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I created a patch that will return true when there isn't a user defined handler, but would return the value set as the handler. It would be string, if string, or array if array.

This can be helpfull when you need to restore previous handler Test script: --------------- <?php declare(ticks = 1); function sig_handler($signo) { switch ($signo) { case SIGTERM: exit; break; default: } } // this will return previous handler for SIGTERM signal $previous_handler = pcntl_signal(SIGTERM, "sig_handler"); // restore previous handler $previous_handler = pcntl_signal(SIGTERM, $previous_handler); Expected result: ---------------- function pcntl_signal() returns previous value of the signal handler for passed signal on success or FALSE on failure Actual result: -------------- function pcntl_signal() returns TRUE on success or FALSE on failure ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72409&edit=1
