Question

I worked out this regex and its working close but only one more problem in that, it matches any word with more than one period (.)

For example: stuf… (got matched)

How do I limit the period to “Only allow 1 period per set of bracket” in the regex?

'#((\w+://)?(\w+\.)([a-z0-9\-/.?=_&%])+)#i'

Answer 1

Try this:

'#((\w+://)?(\w+)(\.[a-z0-9\-/?=_&%]+)+)#i'

This requires a non-period-char after each period.

But I would recommend something like this:

'#((\w+://)?\w+(\.[a-z0-9\-]+)*\.[a-z\-]{2,}(/[\w\-./?=&%]*)?)#i'
