Re: searching for a special string in an array

It would be less confusing to you and others if you used the customary /.../
for REs.
Double quotes are a particularly poor choice because naturally people will
confuse the text with a string.

last;
}
But it seems to have problems. if I remove the "(s)" it works fine but

You need to escape the parantheses because they are using for grouping in
REs.

I need to find a unique string which contains exactly this: "item(s)".
Any idea ?!?!?

Even better: use the right tool. If you want to search for a substring
within another string then index() is your friend. No need to wield the big
RE cannon for that task.
