Solution to the problem of garbled characters when PHP MySQL Chinese data is saved to the database Method

Common reasons why Chinese garbled characters appear in PHP MySQL:

1. The encoding of the MYSQL database is utf8, which is inconsistent with the encoding format of the PHP web page, which will cause Chinese garbled characters in MYSQL .

2. When creating a table or selecting a field in MYSQL, the type set is not utf8, and the web page encoding is not utf8, which may also cause MYSQL Chinese garbled characters.

3. Character set of the PHP page The encoding is inconsistent with the database.

4. PHP connects to the MYSQL database. The operation is to set the encoding specified by the statement and the page encoding. The PHP page encoding is inconsistent.

5. If the encoding of the HTML page submitted by the user is inconsistent with the encoding of the page that displays the data, it will definitely cause the PHP page to be garbled.

Methods to solve the problem of Chinese garbled characters:

1. Web page encoding settings. Generally, add the attribute:

to the file header 100db36a723c770d327fc0aef2ce13b1 in the HTML code to ensure that the web page is "utf-8" encoded.

2. PHP code settings. Add the following code at the beginning of the php code:

header("Content-type: text/html;charset=utf-8");

and the encoding method of the saved file is required to be utf-8 (you can use EditPlus to open the settings, as shown below), thus ensuring that the file is also utf-8 encoded .

3. The Chinese part stored in the fields of the table in the database must be set to the utf8_general_ci type.

4. When PHP connects to the database for operation, it is necessary to set the field type of the operation to utf8. The setting method is as follows:

mysql_connect('localhost','user','password'); mysql_select_db('db'); mysql_query("set names utf8"); //**设置字符集*** mysql_query(要执行的sql语句);
