Req #69269 [NEW]: Allow assert to execute a closure

From: tom at r dot je Operating system: any PHP version: 5.6.6 Package: *General Issues Bug Type: Feature/Change Request Bug description:Allow assert to execute a closure 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 bug report at https://bugs.php.net/bug.php?id=69269&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69269&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69269&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69269&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69269&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69269&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69269&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69269&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69269&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69269&r=support Expected behavior: https://bugs.php.net/fix.php?id=69269&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69269&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69269&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69269&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69269&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69269&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69269&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69269&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69269&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69269&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69269&r=mysqlcfg
