eregi in an IF statement....

I'm attempting to fix a little flaw that I have. I have a legacy database which has a mix of 10 and 7 digit phone numbers in it. I first designed the function format_phone with this (under the assumption of 10 digit phone numbers): function format_phone ( $phone ) { $phone = eregi_replace ( "([0-9]{3,3})([0-9]{3,3})([0-9]{4,4})", "(\\1) \\2-\\3" , $phone ); return $phone; } It worked just fine... But when I switched to the code below, it doesn't work with any of the numbers, they all come back as not recognized. if ( eregi ( "([0-9]{3,3})([0-9]{3,3})([0-9]{4,4}))" , $phone , $edit ) ) { //10 digits $phone = "(" . $edit[1] . ") " . $edit[2] . "-" . $edit[3]; } elseif ( eregi ( "([0-9]{3,3})([0-9]{4,4}))" , $phone , $edit ) ) { //7 digits $phone = $edit[1] . "-" . $edit[2]; } else { echo "phone not recognized"; } Any suggestions?
