Bug #68172 [NEW]: Function name must be a string

From: pegasus at vaultwiki dot org Operating system: Centos 6 64-bit PHP version: master-Git-2014-10-07 (Git) Package: Scripting Engine problem Bug Type: Bug Bug description:Function name must be a string Description: ------------ Assuming an object scope, where $info['callback'] = 'callbackMethod' and 'callbackMethod' is a method on $this object. The following code works under 5.6.0: #### $out = $this->$info['callback']($data); #### But in Master it throws a fatal error (Function name must be a string). Changing it to the following and it again works as expected: #### $out = $this->{$info['callback']}($data); #### Unfortunately this code is from another vendor, so I cannot expect them to change this although using curly braces may be better practice in general to specify the proper evaluation order. Expected result: ---------------- No fatal error. -- Edit bug report at https://bugs.php.net/bug.php?id=68172&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68172&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68172&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68172&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68172&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68172&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68172&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68172&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68172&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68172&r=support Expected behavior: https://bugs.php.net/fix.php?id=68172&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68172&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68172&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68172&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68172&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68172&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68172&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68172&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68172&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68172&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68172&r=mysqlcfg
