How to solve the problem of garbled codes in php writing to database?

The problem of garbled codes in the database written by PHP

The problem of converting PHP pages to UTF-8 coding

1. Add a line at the beginning of the code:

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

2.PHP file encoding problem

Click the editor menu: "File"-> "Save as", you can see the encoding of the current file, and make sure that the file is encoded as: UTF-8

If it is ANSI, you need to change the code to: UTF-8.

3.PHP header BOM problem:

PHP files must not have BOM tags

Otherwise, there will be a situation where session cannot be used with a similar prompt:

Warning: session_start () [function.session-start]: Cannot send session cache limiter-headers already sent

This is because when session_start () is executed, the entire page cannot have output, but when there is a BOM tag in the previous PHP page

PHP took this BOM tag as output, so it made a mistake!

So the BOM tag must be removed from the PHP page.

The method to delete this BOM tag:

1. You can use Dreamweaver to open the file, and re-save, that is, you can remove the BOM tag!

two。 You can open the file with EditPlus and set it to "always remove signatures" in the menu "preferences"-> "Files"-> "UTF-8 identity".

Then save the file, you can remove the BOM tag!

When 4.PHP saves the file as an attachment, the UTF-8 encoding problem:

PHP saves the file as an attachment, and the file name must be GB2312 encoded

Otherwise, if there is Chinese in the file name, the garbled code will be displayed:

If your PHP itself is a file in UTF-8 encoding format

You need to change the filename variable from UTF-8 to GB2312:

Iconv ("UTF-8", "GB2312", "$filename")

Use the program to exemplify the character interception method

Function utf8_substr ($str,$len) {for ($itemo / exchange i127) {$iodiac / if ($I)
