Question

I have a table that stores the setting and its value what is the best way to retreve the values form the database?

Settings table is set out like this:

setting    value
 host       1.2.3.4
 port       1234
 user       me
 pass       cake

Eg:

$host = $db->query('SELECT value FROM settings where setting = "host" ');
print $host;

Answer 1

I am Using PDO

$sth = $dbh->prepare('SELECT value FROM settings where setting = :host');
$sth->bindValue(':host', $host, PDO::PARAM_STR);
$sth->execute();
$value = $sth->fetch();
return $value;

This is the recommended way now to react with database.
