Adding line numbers to matched array

[newbtophp]

Hi, I want to use preg_match_all(), but want to add the line numbers to the array for each of the matches, how would this be achieved?

[newbtophp]

I was thinking of integrating file() to retrieve the line nums?, so the final array would consist of the match along with the line number.

 

//matches        //lines nums

$matches = array(

"some match" => 45

);
