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

Edit report at https://bugs.php.net/bug.php?id=68172&edit=1 ID: 68172 Updated by: sixd@php.net 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: See https://wiki.php.net/rfc/uniform_variable_syntax Previous Comments: ------------------------------------------------------------------------ [2014-10-07 03:00:48] pegasus at vaultwiki dot org 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 this bug report at https://bugs.php.net/bug.php?id=68172&edit=1
