WP_Rewrite::preg_index()
Indexes for matches for usage in preg_*() functions.
The format of the string is, with empty matches property value, '$NUM'. The 'NUM' will be replaced with the value in the $number parameter. With the matches property not empty, the value of the returned string will contain that value of the matches property. The format then will be '$MATCHES[NUM]', with MATCHES as the value in the property and NUM the value of the $number parameter.
