插入数据前设置字符编码为utf8

xxx.php保存时选择utf8编码，页头最好加上

header('conten-type:text/html;charset=utf-8');

在执行CRUD操作前先执行一下

mysql_query("set names utf8");

测试代码xxx.php如下：

<?php

header('conten-type:text/html;charset=utf-8');

mysql_connect("localhost", "root", "password") or die("Could not connect: " . mysql_error());

mysql_select_db("test");

mysql_query("set names utf8");

$str = "CHN 软件开发有限公司,JPN ソフトウェア開発株式会社,KOR 소프트웨어 개발 유한 공사,RUS Суд программного обеспечения".time();

$sql = "insert into tablename4 (varchar1, varbinary1 ) values ('".$str."','".$str."')";

echo $sql."<hr>";

mysql_query($sql);

$result = mysql_query("SELECT id, varchar1 ,varbinary1 FROM tablename4");

while ($row = mysql_fetch_array($result, MYSQL_BOTH)) {

printf ("ID: %s , varchar1: %s, varbinary1: %s<br>", $row[0], $row["varchar1"], $row["varbinary1"]);

}

mysql_free_result($result);

?>
