Using Scala pattern matching to find whether a List contains a value -

-

i've seen range of different matches can against list using pattern matching. possible use pattern matching identify if (and ideally which) element in list contains value x? this: 

def contains(text: list[char], chr: char): boolean = text match{   case *pattern matching chr value in text* => true   case _ => false }

just trying learn can , can't do.

(i know can use text.contains(chr), btw)

thanks, peter

what have seen use matching on list recurse, in case probably:

def contains(text: list[char], chr: char): boolean = text match{   case head :: tail  => head.equals(chr) || contains(tail, chr)   case nil => false }

i don't think can use match kind of operations because of how unapply method of list defined, theoretically if know length of list write like

case x1 :: x2 :: x3 // , on

but guess can see not practical nor ideal param-matching.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
