Illegal string offset

Reports the usages of non-integer offsets in string access expressions such as $str[42].

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 ( for details.
