You might want to take a look at this question:

Detect encoding and make everything UTF-8

especially the second answer by Sebastian Grinoli

He wrote a class (and offers the link to it) which would correctly encode Windows Extended ASCII to UTF8 and also correct UTF8 if necessary.

A really handy tool to have when you are in the UTF8 land :)

回答2:

did you try this code ?

   mysql_query('set names utf8'); 

回答3:

Take a look at utf8_encode to do this for you. Keep in mind this will only work if your data is actually UTF-8 encoded. Unfortunately there is no way to just look at the string and see what encoding it's using.

For me works following code:

$mysqli = mysqli_connect( ... ); mysqli_query( $mysqli, 'SET NAMES "utf8" COLLATE "utf8_general_ci"' );

or just:

mysqli_set_charset( $mysqli, 'utf8' );

Regards, good luck!
