Preface

This article mainly introduces to you the ultimate solution to the Chinese garbled problem in PHP, and shares it for your reference and study. At the beginning Before, let’s talk about why Chinese garbled characters appear?

When many novice friends learn PHP, they find that the Chinese in the program will be garbled when output. So why does this garbled situation occur? Generally speaking, there are two reasons for the appearance of garbled characters. One is due to the incorrect encoding (charset) setting, which causes the browser to parse with the wrong encoding, resulting in a screen full of messy "heavenly books". The second is that the file is If you open it with the wrong encoding and then save it, for example, if a text file is originally encoded in GB2312 but is opened in UTF-8 encoding and then saved, garbled characters will appear. This article will show you how to solve the problem of garbled characters in PHP.

We divide the garbled code situation into the following types. If necessary, you can refer to the following situations to solve the garbled code problem in a targeted manner

The first type: Solve Methods for garbled Chinese characters in HTML

If your HTML file has garbled characters, you can add UTF8 encoding (international encoding) to the head tag: UTF-8 is not available National coding is independent of any language and can be used in any language.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

Our current HTML5 file, set the encoding For simplicity, like the following

Second, HTML and PHP mixed page solution

How to mix HTML and PHP, in addition to following the operations mentioned in the first method, you also need to add this code at the top of the PHP file:

<?php
header("content-type:text/html;charset=utf-8");  //设置编码
 
?>

The third type is the problem of Chinese garbled characters in pure PHP pages (the data is static)

If your PHP page has garbled characters, just Just add the following code at the beginning of the page.

<?php
header("content-type:text/html;charset=utf-8");  //设置编码
?>

##The fourth type, PHP Mysql Chinese garbled problem

<?php
 mysql_query(&#39;SET NAMES UTF8&#39;);
 //接下来的就是查出数据或者修改，增加
?>

One thing to note: The mysql_query("set names 'coding'"); code added before the PHP program that needs to perform database operations must be consistent with the code. PHP encoding is consistent. If PHP encoding is gb2312, then mysql encoding is gb2312. If it is utf-8, then mysql encoding is utf8. In this way, garbled characters will not appear when inserting or retrieving data.
