Bug #77966 [NEW]: Cannot alias a method named "namespace"

From: mattacosta at gmail dot com Operating system: PHP version: 7.3.5 Package: Scripting Engine problem Bug Type: Bug Bug description:Cannot alias a method named "namespace" Description: ------------ Methods may use semi-reserved keywords, however it is not possible to alias a method named "namespace". According to the error, the alias statement somehow becomes equivalent to 'as as bar'. Test script: --------------- <?php trait A { function namespace() {} } class C { use A { namespace as bar; } } Expected result: ---------------- No error. This should be no different than if the method were named 'foo' and then using 'foo as bar'. Actual result: -------------- Fatal error: An alias (bar) was defined for method as(), but this method does not exist in /in/DmNne on line 7 -- Edit bug report at https://bugs.php.net/bug.php?id=77966&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77966&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77966&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77966&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77966&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77966&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77966&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77966&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77966&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77966&r=support Expected behavior: https://bugs.php.net/fix.php?id=77966&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77966&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77966&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77966&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77966&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77966&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77966&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77966&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77966&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77966&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77966&r=mysqlcfg
