Code

function _dfp_token_replace_make_key($text, array $data) {

  // $text may be arbitrarily long, which can slow-down lookups. Hashing it
  // keeps uniqueness but guarantees a manageable size. Since this value won't
  // be used as the cache key itself we're not limited to 255 characters but
  // it will be nicer on array lookups in PHP.
  $keys[] = sha1($text);
