find exact word

[mysterbx]

hola,

 

what delimeter should i use to find an exact word in a pettern..

 

example:

$pass = "login";
if(preg_match("#(login|register|signup)#", $pass, $passwordcheck2)) { echo "do somethin"; }

 

the preg match would find a match

 

example #2 (preg match should find a match)

 

$pass = "loginregister";
if(preg_match("#(login|register|signup)#", $pass, $passwordcheck2)) { echo "do somethin"; }

Word Boundaries.

I tried preg_match("\b(login|register|signup)\b", $pass, $passwordcheck2)

 

doesnt work...

i read that article, but I dont know how to match the one word only... if preg match finds the needed word, it doesnt count it...

[mysterbx]

got it:

 

preg_match("~^\bjoin\b$~", $pass2, $passwordcheck2))

 

but how can i match word "join" to "JOIN" (join=JOIN=jOIN=Join) ... i think you get the point...

There's no need to use word boundaries if you're using anchors.

 

/\Ajoin\z/i
