[SOLVED] help with mac address

[solarisuser]

Hello All,

 

I have data in the form of "0:1:22:33:44:55" and "00:11:22:33:44:55".

What I would like to figure out is how to have regex modify the first example to add a "0" in front of any single digit or alpha character, and leave the parts with two numbers or alphas alone.  The ":" is always going to be a delimiter.

 

For example, the first example above should convert to "00:01:22:33:44:55".

 

Any assistance would be appriciated - I have basic regex experience and use google to figure out basic stuff but I dunno how I would start this.

 

Thanks

Mac address' are in hexadecimal rapresentation, if i'm not wrong, so you have also to consider letteral characters, something like this

 

echo preg_replace('/\b[A-F0-9]\b/i','0$0',$mac);
