Bug #55573 [NEW]: "Undefined variable" when calling closure/anon function from static property

From: Operating system: Mac OS X PHP version: 5.3.8 Package: Scripting Engine problem Bug Type: Bug Bug description:"Undefined variable" when calling closure/anon function from static property Description: ------------ When trying to call a function stored in a static property I get the "Undefined variable" notice and a "Function must be a string" fatal error. This happens whether or not the function is stored directly in the property or in an array. A work around (for now) seems to be storing the property into a temp variable. Test script: --------------- // Test Case 1: class Foo { public static $bar; } Foo::$bar = function() { echo 'Foo bar!'; }; Foo::$bar(); // Work around: /* $f = Foo::$bar; $f(); */ // Test Case 2: class Foo { public static $bar = array(); } Foo::$bar['bar'] = function() { echo 'Foo bar!'; }; Foo::$bar['bar'](); Expected result: ---------------- Foo bar! Actual result: -------------- Notice: Undefined variable: bar Fatal error: Function name must be a string -- Edit bug report at https://bugs.php.net/bug.php?id=55573&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55573&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55573&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55573&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55573&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55573&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55573&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55573&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55573&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55573&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55573&r=support Expected behavior: https://bugs.php.net/fix.php?id=55573&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55573&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55573&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55573&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55573&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55573&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55573&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55573&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55573&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55573&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55573&r=mysqlcfg
