MySQLi - Set Charset

语法

bool mysqli_set_charset ( mysqli $link , string $charset )

定义和用法

它设置默认的客户端字符集。

示例

试试下面的例子 −

<?php
   $servername = "localhost:3306";
   $username = "root";
   $password = "";
   $dbname = "TUTORIALS";
   $tmp = NULL;
   $conn = new mysqli($servername, $username, $password, $dbname);

   if (!$conn->real_connect($servername, $username, $password, $dbname)) {
      die('Connect Error (' . mysqli_connect_errno() . ') '. mysqli_connect_error());
   }
   echo 'Success... ' . mysqli_get_host_info($conn) . "
";
   printf("character set: %s
", $conn->character_set_name());

   if (!$conn->set_charset("utf8")) {
      printf("Error loading character set utf8: %s
", $conn->error);
      exit();
   } else {
      printf("Current character set: %s
", $conn->character_set_name());
   }
   
   $conn->close();
?>

上述代码的示例输出应该是这样的 −

Success... localhost:3306 via TCP/IP character set: latin1 Current character set: utf8
