What code to use for php garbled code?

PHP garbled code problem is a relatively common problem, and it is especially important for Chinese websites. If there is garbled code in your website, you need to use some code to solve it. This article will introduce how to solve the problem of PHP garbled code.

1. Reasons for PHP garbled characters

1. The current file encoding method does not match: If the encoding method of the PHP program file is inconsistent with the encoding method of the current PHP running environment, garbled characters will occur. .
2. Database encoding method does not match: If the encoding method of the database is inconsistent with the encoding method of the page when using PHP to access the database, garbled code problems will occur.
3. Browser readers are inconsistent: Different browsers or different readers have different processing methods when reading web page codes, which may also lead to garbled code problems.

2. Code to solve the problem of PHP garbled characters

1. Character encoding settings

In PHP, you can use the header() function to encode characters Encoding settings so that the output content can display Chinese correctly.

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

Just put the above code at the top of the PHP program file.

2. HTML header settings

Similarly, encoding settings can also be made in the tag of HTML.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Put the above code in the tag.

3. Database encoding settings

Before accessing the MySQL database, you need to set the MySQL character set. Under normal circumstances, just set MySQL's character set to UTF-8.

mysql_query("SET NAMES utf8");

Just place the above code before accessing the MySQL database.

4. Output data encoding conversion

If garbled data is output in the PHP program, you can use PHP's iconv() function to perform encoding conversion.

$output = iconv('GBK', 'UTF-8', $input);

Replace $input in the above code with actual garbled data.

5. File encoding conversion

If the encoding method of the PHP program file is inconsistent with the encoding method of the current PHP running environment, you can use the iconv() function to perform encoding conversion.

$contents = file_get_contents('file.php');
$contents = iconv('GBK', 'UTF-8', $contents);
file_put_contents('file.php', $contents);

Replace 'file.php' in the above code with the actual PHP program file.

3. Summary

The above is the solution to the PHP garbled problem and the corresponding code. By setting character encoding, modifying HTML headers, setting database character sets, output data encoding conversion, and file encoding conversion, we can effectively solve the problem of PHP garbled characters. One final thing to note is that although the above code can solve most garbled code problems, if the garbled code problem is very complex or unrelated to the above problems, some in-depth research and debugging will be required to find the real solution.
