eregi not working

Can someone tell me why this isn't working? To me it say open the file, read it, stick into a variable, close the file. Then search that variable (the file) and look for the eregi statements. Can someone tell me why this only gets the first instance of what I'm searching for? Thanks a bunch. #!/usr/bin/php -q <? $site = "proxy.html"; $open = fopen($site, "r"); $contents= fread($open,filesize($site)); fclose($open); $search=eregi("[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}", $contents,$array); echo $array[0]; echo $array[1]; echo $array[2]; ?>
