Well, I think I'd approach this using preg_match_all() to break out all your elements for replacement into an array, then look them up and produce a second array of the desired replacements, and then do a preg_replace using those two arrays to do your desired replaces. Something like (completely untested!): $matches = preg_match_all('|\[(.*\)]|U', $sentence, $items); if ($matches): $replacements = array(); foreach ($items[1] as $i=>$item): $replacements[$i] = /* random item looked up in "$item.php" */; $items[1][$i] = '|\['.$item.'\]|'; // reconstruct as valid preg pattern endforeach; $new_sentence = preg_replace($items[1], $replacements, $sentence); endif; Cheers!
