I'm trying to define a few environment variables for a PHP application but one of these variables contains the "$" sign. When I test the configuration file with nginx -t
, I get an error message telling me that a variable does not exist. It seems to interpret the text after "$" as a variable name, which is of course not defined.
Maybe I did not search in the right places, but I couldn't find information about how to escape the "$" character. Is that possible and how can it be done?
Update: I tried to enclose the value between single quotes and double quotes following d3ag0s's comment but I had the same error message.

According to this page, it is not possible to escape the $ sign, but they provide a workaround:

Although it might not be the best solution, I have tested it and it works.
