regular expression to extract from the middle of a string

Hey folks I don't want to "just get you to do the work", but I have so far tried in vain to achieve something... I have a string similar to the following; cn=emailadmin,ou=services,dc=domain,dc=net I want to extract whatever falls between the 'cn=' and the following comma - in this case 'emailadmin'. Question(s); is this possible via a regular expression? does php have a better way of doing this? Some pointers would be greatly appreciated. Once I have working, I will be creating a function which will cater for this and will post to this list if anyone is interested?
