How to make search for occurrence of text with recursion in grep in certain extensions?

Question

linux

Tell me how to do a recursive grep search in all directories so that it checks only *.php files?

grep -rl "some-words" "*.php$"
grep: *.php$: No such file or directory

it turns out to run grep either only with recursion, but without expansion restriction or without recursion, but with expansion

Answer 1

grep -r --include=*.php "some-words" /path
