HomeBackend DevelopmentPHP ProblemHow to set default encoding to UTF-8 in php

PHP is a widely used open source server scripting language for web development and is ideal for processing HTML form data. When we operate strings in PHP, we sometimes encounter encoding problems, such as some non-English characters being garbled. This is because PHP's default encoding is ISO-8859-1, not UTF-8. Therefore, PHP's default encoding needs to be set to UTF-8. So, how to set it up?

Method 1: Edit the php.ini file

php.ini is the configuration file of PHP. We can change the default encoding of PHP by modifying it. In the php.ini file, find the settings in the following two lines:

; Default charset for scripts. This default is used in absence 
; of any charset specified in HTTP headers or meta charset tags 
default_charset = "ISO-8859-1"

Set default_charset to "UTF-8" and comment out ";". The modified code is as follows:

; Default charset for scripts. This default is used in absence 
; of any charset specified in HTTP headers or meta charset tags 
default_charset = "UTF-8"

Method 2: Use PHP’s ini_set function

If the php.ini file cannot be accessed on the server, you can use the ini_set function to set the default encoding. The method is as follows:

ini_set('default_charset', 'UTF-8');

Set default_charset to UTF-8 through the ini_set function to change PHP's default encoding.

Method 3: Use the .htaccess file

The .htaccess file is an Apache server configuration file used to control the configuration of the file server at the directory level. In the .htaccess file, setting the default encoding of PHP can be achieved by adding the following code:

AddDefaultCharset UTF-8

Note: If there is already code to set the encoding in the PHP script, the default encoding setting will be invalid. Therefore, you can add the following code at the head of the PHP script to ensure the correctness of the PHP encoding settings:

header('Content-Type: text/html; charset=UTF-8');

Summary

The above are three ways to help set the PHP default encoding to UTF- 8 method. Under normal circumstances, we will choose the first method of modifying the php.ini configuration file to set it. No matter which method is used, it can help us solve the problem of PHP garbled code and ensure the stability and correctness of PHP application operation.
