Sure.
Now you wanna go re-write all my code that pre-dates preg_* functions
being added to PHP? :-)
Un-paid? :-) :-) :-)
Cuz I probably still do have a while(ststr(...)) str_replace() loop or
two in there somewhere from PHP3.0rc2 days...
Yes, ereg_* were in then.
But they were kinda slow and I didn't undestand Regex then.
Hell, I barely understand it now, really.
There's a certain point where the Regex expression reaches a level of
complexity that I'm just not willing to accept in my code and call it
"maintainable"
/ */ is fine, of course.
But there's lots of times when I know there must be a one-line regex
to replace 10 lines of code, but I don't WANT to use it because I'll
stumble over that one-line Regex every time I have to change it.
