Bug #81303 [NEW]: Error message for match() is misleading and unhelpful

From: crell Operating system: Linux PHP version: 8.0.8 Package: Scripting Engine problem Bug Type: Bug Bug description:Error message for match() is misleading and unhelpful Description: ------------ When a match() statement finds no matching arm, it throws an exception. The exception's error message text, however, is very generic. Specifically, it reads "Unhandled match value of type $type_of_the_match_var". The type of the variable is rarely useful in that case. The *value* of the variable is what didn't match, so that's what should be in the message. However, it's not even in the thrown object at all. Test script: --------------- try { $v = match('float') { 'string' => 's', 'int' => 'i', }; var_dump($v); } catch (UnhandledMatchError $e) { var_dump($e); } Expected result: ---------------- An exception thrown with a less misleading error message string, including the value of the variable, not its type. Actual result: -------------- object(UnhandledMatchError)#1 (7) { ["message":protected]=> string(36) "Unhandled match value of type string" ["string":"Error":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(9) "/in/U4Ns2" ["line":protected]=> int(4) ["trace":"Error":private]=> array(0) { } ["previous":"Error":private]=> NULL } -- Edit bug report at https://bugs.php.net/bug.php?id=81303&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81303&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81303&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81303&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81303&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81303&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81303&r=support Expected behavior: https://bugs.php.net/fix.php?id=81303&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81303&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81303&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81303&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81303&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81303&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81303&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81303&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81303&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81303&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81303&r=mysqlcfg
