File | Settings | Language Injection - Generic PHP for Windows and Linux PhpStorm | Preferences | Language Injection - Generic PHP for macOS Ctrl+Alt+S
The dialog opens when you click in the Language Injection page, and choose Generic PHP on the context menu, or select an entry and click .
PhpStorm comes with a set of predefined injection configurations which is quite sufficient to ensure high productivity and comfortable environment. Therefore it is strongly recommended that you use the predefined injection configurations and avoid creating new ones.
The name of the injection.
The language to be injected.
ID. The language ID or name.
Prefix. A sequence of characters to be added before the corresponding string value.
Suffix. A sequence of characters to be added after the corresponding string value.
The prefix and suffix are optional.
In this field, 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 to enable more fine-grained control over the injection process.
Single file - If the option is off, the fragments that match the value pattern are treated separately, as different "files" - for example from the fragment editor's viewpoint.
If the option is on, the corresponding fragments are all merged together to form a single unit, or "file".
Given the value pattern
xxx (.+) yyy (.+) zzz
and the fragment
xxx select * yyy from family zzz,
select * and from family are treated as two independent fragments (or "files") if the option is off. If the option is on, select * from family is treated as a single unit or "file".
