If the field has Chinese characters and the PHP file setting encoding is GBK2312, there will be no problem when fetching the database information:

print_r($rs["Customer Code"]);

If If the PHP file is set to encoding utf-8, an error will be reported.

If you must set the encoding of the PHP file to utf-8, you need to convert the encoding:

print_r($rs[mb_convert_encoding("Customer encoding","GBK","UTF -8")]);//Print the record array

This way there will be no problem.
