You've shown me something I'd not seen before. Never used strspn(); until now.
Had to look it up to see what it did. I like it.
I removed the 1st strlen() for it to work (if anyone else tries it) but hey,
you probably typed it from memory.
Something I'm finding harder to do lately :-)
if (strspn(strtolower($addr),
'abcdefghijklmnopqrstuvwxyz0123456789:/._-') != strlen($addr))
I'll definitely put that one in my toolbox for future reference.
I didn't want to be beaten on the regex though, as it looked simple, and it was.
if (preg_match('/[^a-zA-Z0-9\:\/\.\_\-]/', $addr))
Some of the backslashes are not really needed, but they don't hurt, and I could
have used "i" for lowercase.
Must have wasted 2 hours on this. I think I'd just spent too long without a
break.
Many thanks, Bob.
