Completion Languages in php files

[raicabogdan]

Describe the bug
Well I just installed and setup the extension with Mysql driver. I tested it to see it working with normal in a normal .sql file.
The autocompletion works as expected.
Then I tried adding php to the completion languages in the extension settings and checked to see if it works in a simple
$query = "SELECT * FROM tablename";
but the auto completion does not work inside the variable string.
Perhaps I misunderstood the specific setting and it is not intended for this usage?

To Reproduce
Steps to reproduce the behavior:

1. Go to extension settings
2. Add 'php' to the Completion Languages
3. Test in a php file

Expected behavior
Expected auto completion to occur within the variable SQL string.
