Parsed variables in function names incorrectly flagged as syntax errors

Apache NetBeans version

Apache NetBeans 23

What happened

In PHP, function names can be constructed as strings at runtime.

Such a process can involve joining two strings together, one of which is a variable.

These strings could be joined using the concatenation operator ('string_literal' . $stringVariable) or by using double quotes so that PHP parses the variable "string_literal$stringVariable", and this can be done at the actual function call "string_literal$stringVariable"()

If the concatenation operator is used, NetBeans is perfectly happy, but if double quotes and variable parsing is used, NetBeans flags it as a syntax error:

How to reproduce

Enter this code in a PHP file:

<?php
$type = 'int';
$isType = "is_$type"(7);
var_dump($isType);

NetBeans should accept this code without issue, yet it flags it as a syntax error.

It can be verified that there is no such syntax error by running the code. PHP runs the code without errors or warnings, outputting bool(true) (because 7 is an integer).

Did this work correctly in an earlier version?
