Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
PhpIllegalStringOffsetInspection
Starting from PHP 5.4, string offsets have to be either integers or integer-like strings. Since it's considered bad practice to use strings as a string offset, the inspection reports them, as well.
See String access and modification by character (php.net) for details.
You can suppress this inspection by placing the following comment marker before the code fragment where you no longer want messages from this inspection to appear:
//noinspection PhpIllegalStringOffsetInspectionnote
Actual comment syntax will depend on the code language you are working with
