What should I do if the dw php webpage has Chinese garbled characters?
How to solve the problem of Chinese garbled characters in the preview interface of Dreamweaver when running the php file
Doing website development requires dealing with different problems in many countries As for language, we often encounter a mix of Chinese and English. When using Dreamweaver to create and run PHP code, the Chinese preview window sometimes displays garbled characters, but English can be displayed normally.
1. File encoding: refers to the encoding in which the page file (.html, .php, etc.) itself is saved. Notepad and Dreamweaver will automatically recognize the file encoding when opening the page, so there will be less problems. However, ZendStudio does not automatically recognize the encoding. It will only open the file with a certain encoding. If you accidentally open the file with the wrong encoding while working, and save it after making the modification, garbled characters will appear.
Solution: Page settings, title/encoding, set to UTF8
2, page Declaration encoding:
HTML page encoding settingsIn the HTML code HEAD, it can be used to tell the browser what encoding the web page uses. Currently, XXX mainly uses GB2312 and UTF in Chinese website development -8 Two encodings. When using Dreamweaver to create a new php file, you need to declare the format utf-8: 2458c20ad8814e8d5c01cce841c2226d
2458c20ad8814e8d5c01cce841c2226d
1. The database uses UTF8 encoding, and the page declaration encoding is GB2312. This is the most common cause of garbled characters.
At this time, the directly SELECT data in the PHP script will be garbled. You need to use it before querying: mysql_query("SET NAMES GBK"); to set the MYSQL connection encoding to ensure that the page declaration encoding is consistent with the setting here. The specified connection encoding is consistent (GBK is an extension of GB2312). If the page is UTF-8 encoded, you can use: mysql_query("SET NAMES UTF8");
PHP encoding setting
Write the first sentence in the php code:
<?php header("Content-type:text/html;charset=utf-8"); ?>
Modify the php.ini file
Modify "/etc/php5/apache2/php.ini" and change
default_charset = "iso-8859-1"
to default_charset = "utf-8"
Mysql encoding settings
<?php mysql_query('SET NAMES UTF8'); ?>
Note that it is UTF8 instead of the commonly used UTF-8. If the encoding of the page declaration is consistent with the internal encoding of the database, you do not need to set the connection encoding.
The data input and output of MYSQL is more complicated than what is mentioned above. There are 2 default encodings defined in the MYSQL configuration file my.ini, which are default-character-set in [client] and [mysqld]. The default-character-set is used to set the encoding used by the client connection and the database internally by default. The encoding we specified above is actually the command line parameter character_set_client when the MYSQL client connects to the server, which tells the MYSQL server what encoding the client data received is, instead of using the default encoding.
Based on the previous ones, you also need to add database coding before querying/modifying/adding your data.
2. The page declaration encoding is inconsistent with the encoding of the file itself. This rarely happens because if the encoding is inconsistent, what the artist sees in the browser when creating the page will be garbled. More often than not, it is caused by fixing some minor bugs after release, opening the page in the wrong encoding and then saving it. Or you use some FTP software to directly modify files online, such as CuteFTP. Due to incorrect software encoding configuration, the wrong encoding is converted.
3. When renting a virtual host, if the above three encodings are set correctly, sometimes there are still garbled characters. For example, if the web page is encoded in GB2312, it is always recognized as UTF-8 when opened by browsers such as IE. The HEAD of the web page has already stated that it is GB2312. After manually changing the browser encoding to GB2312, the page displays normally. The reason is that the server Apache sets the global default encoding of the server and adds AddDefaultCharset UTF-8 in httpd.conf. At this time, the server will first send the HTTP header to the browser, and its priority is higher than the encoding declared in the page. Naturally, the browser will recognize it incorrectly. There are two solutions. Administrators should add AddDefaultCharset GB2312 to the configuration file of their own virtual machine to override the global configuration, or configure it in .htaccess in their own directory.
Summary: To solve the Chinese garbled code in PHP, the fastest solution is to make the encoding declared on the page consistent with the internal encoding of the database. If the page number applied for the page is inconsistent with the internal encoding of the database, set the connection encoding, mysql_query ("SET NAMES XXX "); XXX is the connection code. Such as mysql_query('SET NAMES UTF8'); [2]
Finally, Chinese is successfully displayed:
