RegExp for removing text between parenthesis

[Colossus]

Hi,

I have a string like this:
GeboGebo Wiki 0.9.2 (Default branch)

I want to remove the words between the parenthesis. I tried this regexp:
/\([a-zA-Z0-9]\)/ but without success, what is wrong with it ?

Thank you,

You're looking for *exactly one* character a-z or 0-9.

RegExp /\([a-z0-9\ ]+\)/ might work a bit better. Though, it takes the
parenthesis with the contents, and I don't know if that's the wanted
behaviour (you said you wanted to remove the *text* between
parenthesis).

If your string is, as you say, like that, why not use the
string functions instead?

substr($subject ,0,strpos($subj ect,'('))

Your character class doesn't allow spaces and only matches a
single character and the surrounding brackets.

`\([a-z ]+\)`i

Thank you, it works ! I don't know php; can the substr be used as a
replacement of the regexp `\([a-z ]+\)`i ? Which is faster ?

The regular expression matches letters and spaces and the
surrounding brackets, whereas the substr returns everything
up to the first '('. The equivalence of their output
depends on your subject string.

I don't know. Can you tell me?
