mysql中文乱码，phpmyadmin乱码，php乱码产生原因及其解决方法

mysql> select * from mysqlcode;
+----+-----------+
| id | content |
+----+-----------+
| 1 | php爱好着 |
+----+-----------+
1 row in set (0.00 sec)

在没有指定字符集gbk时读取也会出现乱码，如下

mysql> select * from mysqlcode;
+----+---------+
| id | content |
+----+---------+
| 1 | php??? |
+----+---------+
1 row in set (0.00 sec)

【在phpmyadmin创建数据库,并指定字符集】

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018560.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018560.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

表类型根据自己需要选，这里选MyISAM(支持全文检索);
整理选择 gbk_chinese_ci 也就是gbk字符集
gbk_bin 简体中文, 二进制。gbk_chinese_ci 简体中文, 不区分大小写。

在刚才创建的数据库插入数据库

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018561.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018561.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

再浏览时发现是乱码
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018562.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018562.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

为什么呢？是因为数据库为gbk字符集，而我们操作时没有指定为gbk
回到数据库首页
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018563.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018563.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

可以看到 mysql 连接校对默认的latin1_bin。我们将其改为gbk_chinese_ci
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018564.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018564.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

再插入一条数据。看，这条已经正常了
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018565.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018565.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

【解决php读取数据库乱码】

仍以数据库mysqlcode为例

CODE:

[Copy to clipboard]

<?php  

$conn = mysql_connect("localhost","root",""); 

mysql_query("set names 'gbk'");//这就是指定数据库字符集，一般放在连接数据库后面就系了 

mysql_select_db("test"); 



$sql = "select * from mysqlcode"; 

$result = mysql_query($sql,$conn); 



?> 

<head> 

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> 

<title>mysql 字符编码</title> 

</head> 



<body> 

<table width="300" height="32" border="1" align="center" cellpadding="0" cellspacing="0">  

  <tr> 

    <td width="71" align="center">id</td> 

    <td width="229" align="center">内容</td> 

  </tr> 

 <?php while($row = mysql_fetch_assoc($result)){ 

 echo "   

 <tr> 

    <td align=\"center\">".$row['id']."</td> 

    <td>".$row['content']."</td> 

  </tr>"; 

}?>   

</table> 

</body> 

</html> 

<?php mysql_free_result($result);?>

如果我们将mysql_query("set names 'gbk'");注释掉，肯定时乱码
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018566.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018566.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

加上那句又正常了
screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" onclick="if(!this.resized) {return true;} else {window.open('/ddimg/uploadimg/20061129/1018567.jpg');}" alt="" src="http://www.souzz.net/ddimg/uploadimg/20061129/1018567.jpg" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\nCTRL+Mouse wheel to zoom in/out';}" border=0>

一句话
你数据库用什么编码，在对数据库操作之前就set names '你的编码';

ps:页面申明编码：在HTML代码HEAD里面，可以用<meta http-equiv="Content-Type" content="text/html; charset="XXX" />来告诉浏览器网页采用了什么编码，目前中文网站开发中主要用的是GB2312和UTF-8两种编码。
