&quot;AND&quot; in the regexpr

"AND" in the regexpr

Hi!

I have a very stupid question:
for the "OR" there is a "|"-sign in the POSIX-regular expressions. How do I interprate the "AND"??

For ex. I want to search for 2 words in the string: mother AND father. (one or more times)

(mother)+(father)+ doesn't work!!! :-(

Not sure about this one, there is always the possiblity of doing two regular expression searches. Or alternatively doing;

((mother+).(father+))|((father+).(mother+))

I'm sure there is a better way, but i've never done this before, anyone got a better suggestion?

HTH

Regexps match a pattern, a sequence of characets. Not parts of a pattern in random order.

Hence there is no AND, it would serve no purpose.

If you want to match on 'mother' and 'father' in random order, you'll have to define a new pattern for each order that matches.

echo preg_match("/(mother)+.(father)+|(father)+.(mother)+/", $sString);
