mysql - PHP/SQL Check if a similar entry already exists in the database -

-

i have search on website , im trying show list of popular search terms on site sort of works isn't matching strings close enough.

this i'm using:

$sql = "select * db r_name '%".$searchname."%' or r_number '%".$searchname."%'

however if user searches game name , searches game name (reviews) add 2 entries database, there way similarity test before entering entry ?

yes, there way requires fiddle little. there search called soundex, match things close. might not perfect solution question, might started in right direction.

select * db soundex( db.r_name ) soundex( '{$searchname}' );

i believe if have entry 'lowercasexd' , , soundex like('what lowercasexd?'), find entry that's associated 'lowercasexd'. aware type of search take little while run compare '=' searches on indexed databases(on database 5-6k entries per second) not recommended big. if want near-perfect solution, suggest read google's search mechanism, , search engine source code if project significant enough.

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