Formula as text inside PHP

[toplisek]

I have an issue that it is formula inside family font like family=Exo+2
How to manage this as text as it will not be shown on a website due to PHP formula but it should be as text inside a variable.
Need help.

If you encapsulate it with single or double quotation marks, it should be taken for a string by PHP and not be processed otherwise.
