Solution to PHP display garbled characters and apache internal encoding problem

Encoding problem

The default encoding of PHP is utf-8. During the test, for the convenience of not writing the meta tag of the html code, there will be no garbled characters

E:\OpenStudy\www\CSphp

And the help document I downloaded The html version of electronic data requires gb2312 settings

E:\OpenStudy\www\Electronic Books

When starting to configure the server, PHP uses the utf-8 encoding method that is recommended by everyone

[php.ini]
default_charset = "UTF-8"

Server root directory:

E:\OpenStudy\www

AddDefaultCharset 指令

If and only if the response content is text/plain or text/html, this command will add the default value in the HTTP response header. character set. Theoretically this will override the character set specified via the tag in the document body, but actual behavior usually depends on the user's browser settings. AddDefaultCharset Off will disable this feature. AddDefaultCharset On will enable Apache's internal default character set, iso-8859-1. You can also specify to use another charset from one of the IANA registered character set names. For example:

AddDefaultCharset utf-8

AddDefaultCharset should only be used in the following situations: all text resources use the same certain character set, and it is very troublesome to mark their character sets separately. One such example is adding character set parameters to resources containing dynamic content (such as legacy CGI scripts), which may lead to cross-site scripting attacks by including user-supplied data in the output. But please note: A better solution is to modify or delete these scripts, because setting the default character set will disable the browser's automatic character set detection function.

AddCharset 指令
说明 在给定的文件扩展名与特定的字符集之间建立映射

模块 mod_mime

The AddCharset directive establishes a mapping between a specific file extension and a specific character set. charset is the MIME character set parameter of the file with extension as the extension. This mapping relationship will be forcibly added to all existing mapping relationships and overwrite all existing extension extension mappings.

AddLanguage ja .ja
AddCharset EUC-JP .euc
AddCharset ISO-2022-JP .jis
AddCharset SHIFT_JIS .sjis

With the above definition, the document xxxx.ja.jis will be regarded as a Japanese document using the character set ISO-2022-JP (the same is true for the document xxxx.jis.ja). In addition to informing the client of the character set encoding of the document so that it can be translated and displayed correctly, the AddCharset directive is also used for content negotiation (selecting one of several documents to return to the user based on the user's preference information).

and are used to encapsulate a set of instructions so that they only take effect on a certain directory and its subdirectories. Any directive that can be used in the "directory" scope can be used. Directory-path can be a full path to a directory, or a wildcard string containing Unix shell matching syntax. In a wildcard string, "?" matches any single character, and "*" matches any sequence of characters. You can also use "[]" to determine character ranges. None of the above wildcard characters can match the "/" character. So will not match /home/user/public_html, but will match correctly. For example:

<Directory /usr/local/httpd/htdocs> 
　　Options Indexes FollowSymLinks 
</Directory>

Be careful when using the directory-path parameters: they must be consistent with the file system path used by Apache to access files. Directives assigned to a specific will not take effect on the same directory file pointed to by a different path, such as a path generated through another symbolic link.

Solution

1. Comment out the code in php.ini

[php.ini]
;default_charset = "UTF-8"

2. Change the home directory language to

AddDefaultCharset  utf-8

Change the encoding method of the required folder [E:/OpenStudy/www/Electronic Books]

<Directory "E:/OpenStudy/www/Electronic Books">
　　AddDefaultCharset gb2312
</Directory>

The modification is completed, restart apache, and you’re done
