Edit report at https://bugs.php.net/bug.php?id=67757&edit=1 ID: 67757 Updated by: ajf@php.net Reported by: php at tutteli dot ch Summary: multiple default cases Status: Open Type: Bug Package: PHP Language Specification PHP Version: 5.5.15 Block user comment: N Private report: N New Comment: FWIW, I'm also in favour of fixing implementations here. Previous Comments: ------------------------------------------------------------------------ [2014-08-05 23:18:38] pollita@php.net I'd argue that we can look at this either way. It's kind of silly to allow the definition of two defaults in a switch statement, so the question is: Do we define silliness as normal and update the spec, or do we fix a weirdness in the implementation by updating the engine. I for one, vote for the latter. ------------------------------------------------------------------------ [2014-08-05 19:19:15] aharvey@php.net This is probably an issue with the spec, then: AIUI, the spec should be documenting what 5.6 does at present. ------------------------------------------------------------------------ [2014-08-04 12:31:30] php at tutteli dot ch Description: ------------ PHP allows to define multiple default cases in a switch. According to the spec this should not be allowed: https://github.com/php/php-langspec/blob/master/spec/11-statements.md#the-s witch-statement Test script: --------------- <? $a=1; $b=0; switch($a) { default: $b += 1; break; default: $b += 2; } echo $b; //output would be 2 ?> Expected result: ---------------- parser syntax error ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67757&edit=1
