I have been working on a small php app to perform a network scan and fill a database with the discovered information. The issue is that, depending on what you perform the scan with, the MAC addresses are in a number of different formats. This PHP functions validates a MAC and returns false if its not valid or a variety of formats depending on your needs! If anyone has any thoughts on improving this function feel free to let me know and I will post the updates.
