php echo Chinese garbled problem

The Chinese output by echo is displayed as garbled characters.

In fact, various server scripts should encounter this problem.

It is basically an encoding problem.

Generally speaking Considering encoding compatibility, most pages define the page character set as utf-8

. At this time, in order to display Chinese normally, you need to convert the encoding method, such as

echo iconv("GB2312"," UTF-8",'Chinese'); will not be garbled

There are other methods, such as

Add header("Content-Type: text/html; in front of php's echo charset=gb2312”);

Of course, the simplified Chinese page can also be simply,

Change the UTF-8 in to gb2312

At the same time, attach the PHP query database code Operation

<?php
header("Content-Type:text/html;charset=gb2312");
//设置页面字符集
$conn=mysql_connect("localhost", "root", "****");
//****为mysql密码
mysql_select_db("world");
mysql_query("set names utf8");
$sql="select * from city order by population desc";
$res=mysql_query($sql);
echo "<h1>城市信息一览表</h1>";
echo "<table width=&#39;1000px&#39;>";
echo "<tr>";
echo "<td>id</td><td>name</td><td>countrycode</td><td>district</td><td>population</td>";
echo "</tr>";
while($row=mysql_fetch_assoc($res)){
    echo "<tr>";
    echo "<td>{$row[&#39;ID&#39;]}</td><td>{$row[&#39;Name&#39;]}</td><td>{$row[&#39;CountryCode&#39;]}</td><td>{$row[&#39;District&#39;]}</td><td>{$row[&#39;Population&#39;]}</td>";
    echo "</tr>";
}
