Req #77469 [Sus]: Support for multiple empty() arguments - like isset()

Edit report at https://bugs.php.net/bug.php?id=77469&edit=1 ID: 77469 Updated by: nikic@php.net Reported by: rich at milns dot com Summary: Support for multiple empty() arguments - like isset() Status: Suspended Type: Feature/Change Request Package: Variables related Operating System: All PHP Version: 7.2.14 Block user comment: N Private report: N New Comment: Ooops, I mixed up the logic ops. I meant that empty($a, $b) desugars to empty($a) || empty($b) and isset($a, $b) desugars to isset($a) && isset($b). Previous Comments: ------------------------------------------------------------------------ [2019-01-18 11:22:19] nikic@php.net There has been an RFC for this feature, which was declined: https://wiki.php.net/rfc/variadic_empty The reason why this RFC failed is basically that empty($a, $b) must desugar to empty($a) && empty($b), while isset($a, $b) desugars to isset($a) || isset($b). Some people felt that this is confusing. I'm suspending this ticket, as a new RFC proposal would be necessary to accept this feature. ------------------------------------------------------------------------ [2019-01-16 14:37:11] rich at milns dot com Description: ------------ It would be useful if the empty() function also supported multiple function arguments, like isset() does. So basically "are all of these variables empty()". Similar to: Bug #12978: Multiple isset Test script: --------------- e.g. <?php // multiple variables supported by empty() var_dump(empty($var1, $var2, $var3)); // true ?> instead of: <?php // repeatedly calling empty() to check multiple variables $result = (empty($var1) and empty($var2) and empty($var3)); var_dump($result); // true ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77469&edit=1
