Question

I include a PHP file to the HEADER of my WordPress site, which searches through a CSV file and returns me the variable I need. I am trying to have it included in the header because it’s a variable I will need throughout the site later on. If I test it out and try to echo this variable from the included script, it works fine. However, in the rest of the site, if I try to call that variable it doesn’t return anything.

I know that the variable is being created because I try to echo it and it works. But when the I try to use that variable from a different script, it doesn’t work. Is there some kind of code I need to pass the variable over to the rest of the site?

Make sure you global $variable the variable everytime you want to use it in a new function, or even within a new script. This will make sure that the variable is available everywhere that you need it.
