Insert a Whitespace in a String+ eregi_replace()

lucky_php

I have a string like - A and b and ( C or D )

For now, i am taking whitespace as a token so user has to insert whitespace while using (,) ie ( C or D )

I am writing a code so that user wont have to worry about the inserting whitespaces while using ( )-. (C or D) or (C or D ) should work

I want whatever he enters(with/without whitespace) ,my code parses and replaces simple "(" or "( " or " (" with " ( " -- ie whitespace on both sides

Same is for ")"

Is there a way ( may be with eregi_replace ) to do both braces in 1-2 lines?

If I understand correctly:

$text = preg_replace('/ ?(\(|\)) ?/', " $1 ", $text);

Wee simplification?

/ *[()] */

Then " ( " would also be allowed. Replace * with ? if it shouldn't be.

Yeah, after I submitted it I realized a character class would be simpler, but I was too lazy to change it. (Laziness is a theme of mine lately.) I was typing as I was thinking, and I was thinking "open-paren or close-paren", and that's what I typed. 🙂

'Course, I had a typo:

/ *([()]) */

Because we want to remember which paren was seen....
