In this text box, type the rules that define the context where you want PhpStorm recognize literals as injections.
In this area, specify additional settings to narrow the context where the injection is applicable and thus the enable more fine-grained control over the injection process.
Value pattern - in this text box, type a regular expression
that determines the context to inject the language into.
By using the first capturing group of the pattern as the target for injection,
you can configure the procedure to have the language injected only into values that match a certain pattern or
into multiple parts that match the pattern. For example,
Single file - select this check box to specify an exact file to apply the injection to.
