How to solve PHP Chinese output garbled code? Introduction to solutions to garbled Chinese output in PHP

When writing code in PHP, sometimes you may find that the Chinese output has garbled characters. So, how should we solve this kind of garbled PHP output? What we know is that there are generally two situations when PHP outputs garbled characters. One is because the encoding setting is wrong; the other is because the file is opened with the wrong encoding and then saved. In this article, I will show you how to solve Chinese 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 the Chinese in HTML Methods for garbled code problem

If your HTML file has garbled code problem, then you can add UTF8 encoding (international encoding) in the head tag: UTF-8 is a country-less encoding, that is, it is independent of any A language that can be used in any language.

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

Example

For our current HTML5 file, setting the encoding is simpler, like the following

Second, HTML and PHP mixed page solution

If it is a mixed HTML and PHP, in addition to following the operations mentioned in the first method, you also need to be at the top of the PHP file Add this code:

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

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

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

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

The fourth type, PHP Mysql Chinese garbled problem

In addition to following the operations mentioned in the third type, you must also add database encoding before your data query/modification/add. . 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(&#39;SET NAMES UTF8&#39;); //接下来的就是查出数据或者修改，增加
 ?>

If the MySQL version you are using is 4.1 or higher, you can set a character encoding after linking to the database operation, like the following

UTF-8 encoding is just one of the encodings. If you don’t want to use UTF-8 encoding, you can also use other encodings. Just replace UTF-8 with the encoding you want to use. Currently, GB2312 is mainly used in Chinese website development. and UTF-8 two encodings.

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