That is correct, what you say will happen. I'm not the reg-ex god either -- but since nobody else answered, I figured the first thing off the top of my head would be better then nothing. I would say, sed and awk would be a better set of tools for doing this than PHP. Here, as far as I can tell, you might need more than one regex (plus use matches from one rexex in another regex for the replacement). So, here is something that I think does what you want: -- snip -- $array[] = './this/is/1/test.php3'; $array[] = './this/is/2/test.php3'; $array[] = './this/is/3/test.html'; $array[] = './this/is/4/test.php3'; for ($i=0; $i<count($array); $i++) { ereg('([A-Za-z0-9]*).php3', $array[$i], $hits); $array[$i] = eregi_replace($hits[0], 'link_'.$hits[0], $array[$i]); print "\$array[$i] = " . $array[$i] . "\n"; } -- snip -- The output of this is: $array[0] = ./this/is/1/link_test.php3 $array[1] = ./this/is/2/link_test.php3 $array[2] = ./this/is/3/test.html $array[3] = ./this/is/4/link_test.php3 Note: the match ([A-Za-z0-9]) you will also want to fill with possible characters that your files may have.
