Do I need a regular expression?

I have some data that I am putting in a database but I need it modified as it gets inserted.

I have several entries that have two digit years in parentheses. They come in the following formats:

(98) OR (87-92)

I basically want to rewrite them like this:

(1998) OR (1987-1992)

And I also need to check for the condition of a number between 00 and 11 because that would then constitue appending 20 to the beginning rather than 19.

Can anyone help me get started with this?

 

try this:

<?php

$pattern = array('/\b[23456789]\d\b/', '/\b0\d\b/', '/\b[1][0123456789]\b/'); 
$replace = array( '19$0', '20$0', '20$0'); 
$subject = array('94', '11', '03-10', '55', '70-84', '12', '19', '07-14'); 

var_dump((preg_filter($pattern, $replace, $subject))); 

?>

PHP:

 

That worked perfectly and did exactly what I needed. Thank you very much!
