返回值

The function returns a character set object with the following properties:

Collation name

dir

Directory the charset description was fetched from (?) or "" for built-in character sets

min_length

范例

Example #1 mysqli::get_charset() example

面向对象风格

<?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());
