c# - Regular expression MatchCollection returns 1 instead of expected 3 -

-

i have long string in c# it's formatted such \\server\value i've been using regular expression pattern of "(?<='\\\\).*(?=\\)" extract server string. there's use case multiple '\server\value' strings chained '\\servera\value1' + '\\serverb\value2' + '\\serverc\value3'

i'm trying use matchcollection extract server name using pattern (?<=.\\\\).*(>=\\)

the period in first grouping construct account ' character. expect result return 3 occurences returns 1. what's wrong pattern?

   string expression = "'\\\\servera\\value1' + '\\\\serverb\\value2' + '\\\\serverc\\value3'";    string pattern = @"(?<=\\\\).*(?=\\)";     matchcollection matches;    matches = regex.matches(expression, pattern);

if got, i're getting result 

servera\value1' + '\\serverb\value2' + '\\serverc

and want these matches:

servera  serverb  serverc

you can use lazy quantification:

(?<=\\\\).*?(?=\\)

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 $row): ?> <div id="<?=$...
