Bug #54171 [NEW]: is_callable() returns false on callable functions when not specifying namespace

From: Operating system: Ubuntu 10.10 PHP version: 5.3.5 Package: *General Issues Bug Type: Bug Bug description:is_callable() returns false on callable functions when not specifying namespace Description: ------------ First sorry, I can only test this case with PHP 5.3.3 but I didn't find any bugs referring to is_callable() since then, so I think it's worth reporting. The problem is that is_callable() will return false if you don't specify the eventual namespace you're using. Test script: --------------- <?php namespace Foo; function bar() { return 'bar!'; } var_dump(is_callable('bar')); var_dump(is_callable('\Foo\bar')); var_dump(bar()); var_dump(\Foo\bar()); Expected result: ---------------- bool(false) bool(true) string(4) "bar!" string(4) "bar!" Actual result: -------------- bool(true) bool(true) string(4) "bar!" string(4) "bar!" -- Edit bug report at http://bugs.php.net/bug.php?id=54171&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54171&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54171&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54171&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54171&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54171&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54171&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54171&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54171&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54171&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54171&r=support Expected behavior: http://bugs.php.net/fix.php?id=54171&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54171&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54171&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54171&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54171&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54171&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54171&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54171&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54171&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54171&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54171&r=mysqlcfg
