php5.2 iis6 garbled code

When using PHP5.2 and IIS6, you may encounter garbled characters. This is because PHP5.2 is outdated and IIS6 is no longer officially supported. However, many projects still use these old technologies in production environments, so it is also important to solve the problem of garbled characters.

First of all, we need to understand the cause of garbled characters. Generally speaking, garbled characters are caused by inconsistent encoding. When the encoding of the page is inconsistent with the encoding expected by the browser, garbled characters will appear. When using PHP5.2 and IIS6, the following two situations will cause garbled characters:

1. The PHP file encoding is inconsistent with the configuration file encoding.
2. The default encoding of IIS6 is not UTF-8.

For these two situations, we can adopt the following solutions:

1. PHP file encoding is inconsistent with the configuration file encoding

PHP File encoding refers to the encoding of the file itself, while configuration file encoding refers to the encoding of PHP's configuration file. Under normal circumstances, the PHP file encoding should be consistent with the configuration file encoding, otherwise it will cause garbled characters.

In order to solve the garbled code problem in this case, we need to perform the following operations:

1. Set the default encoding in IIS6 to UTF-8 (see below for specific operations).
2. Confirm that the PHP file encoding is consistent with the configuration file encoding. You can use Notepad to open the PHP file and configuration file, click "Save As", select the option with the same encoding in the encoding options, and save.
3. Modify the php.ini file. In the php.ini file, set default_charset to UTF-8, save and restart the IIS6 service.
4. The default encoding of IIS6 is not UTF-8

By default, the encoding of IIS6 is not UTF-8. In order to solve this problem, we need to perform the following operations:

1. Set the default encoding in IIS6 to UTF-8. Right-click "Web Sites" or "Default Web Site" in IIS Manager, select "Properties" or "Properties", then switch to the "HTTP Headers" or "HTTP Headers" tab, select "Default Content" or "Default Select UTF-8 from the "Charset" or "Charset" drop-down menu of "Content" and click "OK" or "Apply".
2. Modify the php.ini file. In the php.ini file, set default_charset to UTF-8, save and restart the IIS6 service.

After performing the above operations, we can easily solve the problem of garbled characters. It is worth noting that although we have solved the garbled problem, it is still recommended to upgrade to a higher version of PHP and IIS to enjoy better performance and more features.
