Bug #55839 [NEW]: Static accessors through variables only work on simple variables

From: Operating system: Windows PHP version: 5.3SVN-2011-10-03 (SVN) Package: Class/Object related Bug Type: Bug Bug description:Static accessors through variables only work on simple variables Description: ------------ Using a static operator ( :: ) works for simple variables ( $foo::function() ), but results in an undefined variable warning for the class name at run-time when using a class property ( ${$bar->foo}::function() ). Obviously, a direct access attempt ( $bar->foo::function() ) fails with a parse error. --- From manual page: http://www.php.net/language.oop5.static --- Test script: --------------- class A { public $referrer = 'B'; } class B { public static function foo() { echo "Foo"; } } $b = 'B'; $a = new A(); $b::foo(); ${$a->referrer}::foo(); $c = $a->referrer; $c::foo(); Expected result: ---------------- I would expect to see Foo Foo Foo Actual result: -------------- This is the result: Foo Notice (8): Undefined variable: B Foo -- Edit bug report at https://bugs.php.net/bug.php?id=55839&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55839&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55839&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55839&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55839&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55839&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55839&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55839&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55839&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55839&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55839&r=support Expected behavior: https://bugs.php.net/fix.php?id=55839&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55839&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55839&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55839&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55839&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55839&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55839&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55839&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55839&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55839&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55839&r=mysqlcfg
