Re: hot to use perg_match with multi strign patern

Hello Your problem is the pattern itself. >if (preg_match("/(yes)?(no)/i", $mesage, $matches)) { > print "refusee - $matches[0]"; >} else { > print "negative"; >}; Your pattern tells the regex to find any 'no' in a text. Since the yes is optional the regex will never check for it. In other words the ()? part is skipped and the no part is tested since the pattern can only match if a no is in the text. The regex will see this and simply ignore the (yes)?. What you probably want is to use alternatives making your pattern look like /(?:yes|no)/i. This way either yes or no is found. Beaware that if you do want to do this it will probably faster to use a string function to find literal occurences. Regards Stefan Langer
