Solution to all garbled characters in PHP editing

PHP is a very popular server-side scripting language used for developing web applications. However, sometimes when we edit PHP files, we find that all Chinese characters have become garbled characters, which brings a lot of trouble to our development work. This article will list some common causes and solutions to help you solve the problem of garbled PHP files.

Cause 1: File saving format error

When we edit a PHP file, if we save the file in a non-UTF-8 encoding format, garbled characters will occur. Therefore, we should save PHP files in UTF-8 encoding format so that there will be no garbled characters.

Solution:

In commonly used editors, such as Sublime Text, Notepad and Dreamweaver, you can set the file saving format. When we save a PHP file, we should select the UTF-8 encoding format to ensure that the character encoding of the file is correct.

Cause 2: Character encoding declaration error

At the beginning of the PHP file, there is usually a character encoding declaration statement, for example:

<?php
header("Content-type:text/html;charset=utf-8");
?>

This statement tells the browser to use UTF -8 encoding to display the page. If there is an error in this declaration statement, it will also cause garbled characters in the PHP file.

Solution:

At the beginning of the PHP file, check whether the character encoding declaration statement is correct. Make sure the correct character encoding is used.

Cause 3: Server configuration error

Sometimes, the problem of garbled PHP files may be caused by server configuration error. If the server is not configured with character encoding correctly or the PHP version is too low, garbled characters will occur.

Solution:

Contact the server administrator to check whether the server's character encoding and PHP version are correct. If there are problems, ask the administrator to configure and upgrade.

Cause 4: The editor default character set is set incorrectly

When using some editors, if the default character set is not set correctly, it will also cause the PHP file to display garbled characters.

Solution:

For Sublime Text, we can select Preferences -> Settings -> User in the menu bar to open the configuration file. Add the following statement to the configuration file:

"default_encoding": "utf-8"

For Notepad, we can select Encoding -> UTF-8 in the menu bar.

Summary

The problem of garbled PHP files is a problem we often encounter during the development process. Through the introduction of this article, we can learn about several common causes and solutions to garbled code problems. In daily development, we should pay attention to the encoding format of the code, correctly configure the server environment, and make good use of the functions of various editors to avoid garbled code problems.
