How do you want it to work?

I’m using preg_match($reg, $_POST[‘matric’]);
I expect the user to enter his matric number in the following format
ebsu/2009/1119
ebsu-2009-1119

ebsu-Is the starting follow by /forward slash of hypen-. I also expect a year 2009,2010 etc… follow by four digit number \d{4}

What about this?

#^ebsu[/-]\\d{4}[/-]\\d{4}$#

Of course, it also accepts ebsu-3333/1119 (- and /, and a year far far in the future).

If you want to check the value of the year more specifically, you could do


preg_match('#^ebsu[/-](\\d{4})[/-]\\d{4}$#', 'ebsu-2009/1128', $matches);
print_r($matches)

It would return


Array
(
    [0] => ebsu-2009/1128
    [1] => 2009
)

and then you can do more specific checks on the value in $matches[1].
