Why doesn't the php variable $ icon appear when pasting a VS Code snippet?

Question

Visual Studio Code

There is such a snippet


But when using it, the $ variable icon is not added to the file with the php extension.


Moreover, if you put this dollar in another place in the snippet, it appears when used, but not in front of the variable, what's the problem?

Answer 1

As far as I remember, in snippets $ is responsible for the cursor position after the snippet is called. shield it.
try using \\$
well, or google how to escape it
