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

Edit report at https://bugs.php.net/bug.php?id=68172&edit=1 ID: 68172 Comment by: pegasus at vaultwiki dot org Reported by: pegasus at vaultwiki dot org Summary: Function name must be a string Status: Open Type: Bug Package: Scripting Engine problem Operating System: Centos 6 64-bit PHP Version: master-Git-2014-10-07 (Git) Block user comment: N Private report: N New Comment: I can accept that vBulletin 4 will not be usable with the next iteration of PHP using vBulletin's official distro (I doubt they are updating that branch anymore). It was easy enough to modify the source on my installation, so it's not an issue for me. Hopefully others won't be caught off-guard by this issue.

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 this bug report at https://bugs.php.net/bug.php?id=68172&edit=1
