Edit report at https://bugs.php.net/bug.php?id=74635&edit=1 ID: 74635 Comment by: spam2 at rhsoft dot net Reported by: shengbin_xu at 163 dot com Summary: when call a disabled function,php not throw a fatal error Status: Duplicate Type: Bug Package: Scripting Engine problem Operating System: ubuntu PHP Version: 7.1.5 Block user comment: N Private report: N New Comment: And this is pretty serious since the following code runs with completely undefined behavior - i reported that months ago and it was argued that the disabled functions are still listed in defined functions in a normal code flow I don't give a damn if a function don't exist at all, is disabled or the extension is not loaded when I just can't call it Since php7 is throwing exceptions everywhere but here and in the soap extension both are just plain bugs and a horrible inconsistency Previous Comments: ------------------------------------------------------------------------ [2017-05-23 07:04:12] requinix@php.net See bug #73921 ------------------------------------------------------------------------ [2017-05-23 05:03:33] shengbin_xu at 163 dot com Description: ------------ in php.ini,popen function is in disable functions: disable_functions => passthru,system,popen,chroot,escapeshellcmd,proc_get_status => passthru,system,popen,chroot,escapeshellcmd,proc_get_status function_exists('popen') return false,but when call popen, php only give a notice,but not throw a fatal error。 Test script: --------------- <?php error_reporting(E_ALL); ini_set('display_errors','on'); var_dump(function_exists('popen'));//false $handle = popen("/bin/ls", "r");//null Warning: popen() has been disabled for security reasons in var_dump($handle); echo gettype($handle); Expected result: ---------------- when popen function is called,php should throw a fatal error。 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74635&edit=1
