The solution to Chinese garbled characters when outputting Chinese pages in PHP

php The problem of Chinese garbled characters often occurs in PHP. Yesterday, I created a file in the local environment. The file encoding is in UTF-8 format. When I printed a simple statement, Chinese garbled characters appeared. It took me a long time to find it. The reason. Let’s solve this problem and record the solution here.

Garbled code problem:

Yesterday I wrote a very simple PHP output Chinese page, but a garbled code problem occurred. The first reaction may be that the encoding format of the script file is incorrect. Question, after looking at it, there is no problem. The original file is encoded as utf-8. What is the reason?

This is the first time I encountered this problem. Although you can add <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> to the output page, It can be temporarily solved, but this method treats the symptoms rather than the root cause and cannot solve the problem at all. Later, I checked online and found that it was a problem with the default character settings of the php.ini configuration.

Solution:

Open the php.ini file, find; default_charset = "iso-8859-1", change it to: default_charset = "UTF-8" Remove the semicolon in front (remove the comment), change the character set to UTF-8, restart the apache service, refresh the page, and the Chinese display will be normal.
