            '[^\w]'. // Must not start with any alphanum or _
            '(?<!->)'. // Must not start with ->
            '('.implode('|', $functions).')'.// Must start with one of the functions
            "\(".// Match opening parentheses
            "[\'\"]".// Match " or '
            '('.// Start a new group to match:
            '.+'.// Must start with group
            ')'.// Close group
            "[\'\"]".// Closing quote
