Store grep output file

Hi, I'm trying to store the output from a grep, I just want the file name.
But couldn't find how to do it.
Basically, I just want to grep <etc> * and I want to store the file name.
There is only one file with the what I'm grepping, so storing in a variable o an array its the same.

If someone could help me, I would appreciate.

grep -l pattern filename

perfect, with -l you get the file name.
But how you store in a variable the filename?

I tried
PHP Code:
response=grep -l pattern

response=$(grep -l pattern *)
response=`grep -l pattern *`
