Simple functions to check & fix if necessary invalid formating of a MAC address... I seem to be having problems with the global variable $mac not being returned from the fix_mac() function. Any help is appreciated. function fix_mac( $mac ) { global $mac;
It's really weird to both pass in $mac as an argument and to declare it global...
Do one or the other, but not both.
quite.
Can't help you with the mess of Regex you've got though...
now I bet you can actually, chicken and egg: you have to have the skill to recognise the mess. ;-)
Jason - don't be dishearted:
a, regexp are/can be hard
b, anyone who is giving them a go, is probably trying hard to improve
their skills (we like that :-)) - regexps are quite a hurdle for most people.
c, we all start out writing regexps like yours (i.e. simple ones) and eventually they become more and more complex/arcane until you become Larry Wall.
