Search for a certain function in all helper files?

you replaced the string "function" with "_helper_test" in the preg_match() pattern that xwero provided. that is wrong. he gave you the pattern and you changed it - i guess because you thought he meant "replace the word 'function' with the name of the function."

copy and paste his preg_match() function verbatim.
