When the AJAX calls the php file, I've noticed the data in the $_POST are garbage data.
I think the problem is during GetXmlHttpObject execution to past the Posted data to php file.
Please teach me to set the charset in AJAX supporting Japanese charset.
Currently, I am using the following settings:
ver 7.4.1 encoding: UNICODE
xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=shift_jis'");
header('Content-Type: text/html; charset=shift_jis');
<meta http-equiv="Content-Type" content="text/html; charset=shift_jis">
