string check

[DuaneCawaling]

$str= "WAL bal";
$message = explode(" ",$word);
if(preg_match('/(register|bal|menu|snacks|drinks|buy|pass)/', $str)){
   if($message[1]){						
       echo "KEYWORD--OK <br>";
       return $str;	
   }else
echo "Invalid keyword, try again.";

 

this works okay, the only problem is that if $str = WAL balance, it is still strue coz it has "bal" and i dont want that to happen..

 

what can i do to limit the $message[1] as such register|bal|menu|snacks|drinks|buy|pass ONLY??

Why use regular expressions at all? in_array does what you (apparently) need.

[DuaneCawaling]

the $str is a string. in_array() needs an array as a parameter. to make the string an array.str_split is used. a problem occurs because the string's parameters 'register|bal|menu|snacks|drinks|buy|pass' are not equal in length.str_split arrays with equal length

Right. But you could just put them in an array instead of a string:

$words = array("register", "bal", "menu", "etc");

[edit] And even if you didn't want to do that, you would have to use explode() (which you've shown you know about) not str_split(). Edited March 6, 2013 by requinix
