Code Inspection: Illegal string offset
Configure inspections: Settings | Editor | Inspections
Show intention actions: AltEnter
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 (php.net) for details.
Place the caret at the highlighted line and press AltEnter or click
