Object oriented style (method):

}

Returns the current character set for the database connection.

## 参数

`link`

  Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()

## 返回值

## 范例

例 1. Object oriented style

`<?php /* Open a connection */ $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } /* Print current character set */ $charset = $mysqli->character_set_name(); printf ("Current character set is %s\n", $charset); $mysqli->close(); ?>`

例 2. Procedural style

`<?php /* Open a connection */ $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (!$link) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } /* Print current character set */ $charset = mysqli_character_set_name($link); printf ("Current character set is %s\n",$charset); /* close connection */ mysqli_close($link); ?>`

上例将输出：

    Current character set is latin1_swedish_ci
