Example #1 mysqli::get_charset() example

<?php
$db = mysqli_init ();
$db -> real_connect ( "localhost" , "root" , "" , "test" );
var_dump ( $db -> get_charset ());
?>
过程化风格
<?php
$db = mysqli_init ();
mysqli_real_connect ( $db , "localhost" , "root" , "" , "test" );
var_dump ( $db -> get_charset ());
?>
以上例程会输出:
object(stdClass)#2 (7) { ["charset"]=> string(6) "latin1" ["collation"]=> string(17) "latin1_swedish_ci" ["dir"]=> string(0) "" ["min_length"]=> int(1) ["max_length"]=> int(1) ["number"]=> int(8) ["state"]=> int(801) }

I guess there's an error in Procedural style example as it contain object oriented code:
var_dump($db->get_charset());
