예 1. visiting every key/value pair in a dbm database
$key = dbmfirstkey ($dbm_id); while ($key) {echo "$key = ". dbmfetch ($dbm_id, $key). "\n"; $key = dbmnextkey ($dbm_id, $key);}

each pair of escape sequences partitions the complete set of characters into two disjoint sets. any given character matches one, and only one, of each pair.
an alternative description is that a subpattern of this type matches the string of characters that an identical standalone pattern would match, if anchored at the current point in the subject string.

dba_fetch() returns the associated string or false, if the key/data pair is found or not found, respectively.
