Preface
This article mainly introduces to you the ultimate solution to the problem of php Chinese garbled characters, and shares it for everyone Please refer to it for reference. Before we start, let’s talk about why Chinese garbled characters appear? (php video tutorial)
When many novice friends learn PHP, they find that the Chinese in the program will be garbled when output, so why does this garbled code appear? What about the situation? 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"/>
Example
Second, HTML and PHP mixed page solution
How to mix HTML and PHP, in addition to following 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 Chinese garbled problem of pure PHP pages (the data is static)
If your PHP page is garbled , just add the following code at the beginning of the page.<?php
header("content-type:text/html;charset=utf-8"); //设置编码
?>Fourth type, PHP Mysql Chinese garbled problem
In addition to following the third operation In addition, you must add database encoding before querying/modifying/adding your data. Moreover, it is worth noting that the UTF8 here is different from the previous one, there is no horizontal line in the middle.<?php mysql_query('SET NAMES UTF8'); //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. The PHP encoding is consistent. If the PHP encoding is gb2312, then the mysql encoding is gb2312. If it is utf-8, then the mysql encoding is utf8, so that there will be no garbled characters when inserting or retrieving data.
