Analyze and solve the problem of garbled characters when forum.php is opened

When using the forum system, we sometimes encounter some problems, one of which is garbled characters when opening the forum.php page. This problem is usually caused by incorrect website encoding format or server-side configuration issues. This article will solve this problem for everyone from these two aspects.

If the website encoding format is correct, but garbled characters still appear when opening the forum.php page, then you need to consider server-side configuration issues. The specific methods are as follows:

1. Modify the Apache server configuration

If we use the Apache server, we need to modify the httpd.conf file to solve this problem. Find the following two lines of code:

AddDefaultCharset off
AddCharset GB2312 .gb2312 .gb

Change AddDefaultCharset off to AddDefaultCharset UTF-8, and change AddCharset GB2312 .gb2312 .gb to AddCharset UTF -8 .utf8, save and restart the Apache server.

2. Modify the PHP server configuration

If we are using a PHP server, we need to modify the php.ini file. Find the following two lines of configuration:

default_charset = "iso-8859-1"
mbstring.internal_encoding = EUC-JP

Change default_charset to UTF-8 and mbstring.internal_encoding For UTF-8, save and restart the PHP server.
