Edit report at https://bugs.php.net/bug.php?id=69269&edit=1 ID: 69269 Updated by: nikic@php.net Reported by: tom at r dot je Summary: Allow assert to execute a closure -Status: Open +Status: Closed Type: Feature/Change Request Package: *General Issues Operating System: any PHP Version: 5.6.6 -Assigned To: +Assigned To: nikic Block user comment: N Private report: N New Comment: PHP 7 will provide an ini option to disable assert without any runtime cost, see https://wiki.php.net/rfc/expectations. Which is what you want, only without having to use a closure. Previous Comments: ------------------------------------------------------------------------ [2015-03-20 12:18:13] tom at r dot je Description: ------------ Currently the manual helpfully states on http://php.net/manual/en/function.assert.php that " The advantages of a string assertion are less overhead when assertion checking is off" Which makes perfect sense. The disadvantages, of course, are that readability is reduced and IDE hints/highlighting won't work and the parser won't immediately catch parse errors in the string. As a happy medium I propose it would be better if assert() could take a closure as it's first argument: assert(function() { return 2 < 1; }); This has the best of both worlds as the code wouldn't be executed unless assertions are turned on. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69269&edit=1
