Discuss the reasons and solutions for garbled Chinese output in php7

In the process of using PHP7 for program development, programmers often suffer from the problem of garbled Chinese output. This article will focus on the reasons and solutions for the problem of garbled Chinese output in PHP7.

Cause of the problem

First of all, we need to understand that in PHP7, the problem of garbled Chinese output is caused by various factors such as encoding method and server environment. The most common reasons include:

1. Inconsistent encoding methods. If the input string encoding method is different from the output encoding method, the Chinese output will be garbled.
2. Server environment issues. If the server itself does not set a good character set, no matter what encoding method is used, the Chinese output will be garbled.
3. Program error. If there are errors in the program itself, such as character set and other factors not being taken into account when concatenating strings, the Chinese output will be garbled.

Solution

To address the garbled Chinese output problem caused by the above reasons, we can adopt the following solutions:

1. Specify the encoding method

If the encoding method of the input string is inconsistent with the output encoding method, you can solve the problem of garbled characters by specifying the encoding method. In PHP7, you can use the mb_convert_encoding() function to convert a string from one standard encoding to another.

2. Set the server character set

If the server itself does not set the character set, no matter what encoding method is used, the Chinese output will be garbled. Therefore, we need to set the character set in the server. For example, in the Apache server, it can be set by adding the following code to httpd.conf:

AddDefaultCharset UTF-8

3. Modify the PHP.ini configuration file

If the server has set the character set, but the Chinese output is still garbled, it may be due to incorrect configuration file settings in PHP.ini. At this time we need to modify the PHP.ini configuration file and change the following options to the corresponding encoding method:

default_charset = "UTF-8"

4. Make sure there are no errors in the program

Finally, we need to make sure there are no errors in the program. Chinese output is garbled. For example, if factors such as the character set are not taken into account when concatenating strings, the Chinese output will be garbled. Therefore, we need to carefully examine possible problems in the program and make corresponding modifications.

Summary

The problem of garbled Chinese output in PHP7 is often caused by a combination of factors. To solve this problem, we need to pay attention to many aspects such as program development and server configuration. I hope the solutions introduced in this article can help everyone solve the problem of garbled Chinese output.
