PHP+AJAX中文乱码问题解决方法

ajax|解决|问题|中文乱码

在PHP从AJAX的来的数据进行转化函数

function utf8RawUrlDecode ($source) {
$decodedStr = "";
$pos = 0;
$len = strlen ($source);
while ($pos $len) {
$charAt = substr ($source, $pos, 1);
if ($charAt == '%') {
$pos++;
$charAt = substr ($source, $pos, 1);
if ($charAt == 'u') {
// we got a unicode character
$pos++;
$unicodeHexVal = substr ($source, $pos, 4);
$unicode = hexdec ($unicodeHexVal);
$entity = "". $unicode . ';';
$decodedStr .= utf8_encode ($entity);
$pos += 4;
}
else {
// we have an escaped ascii character
$hexVal = substr ($source, $pos, 2);
$decodedStr .= chr (hexdec ($hexVal));
$pos += 2;
}
} else {
$decodedStr .= $charAt;
$pos++;
}
}
return $decodedStr;
}

运用以下函数

$formname=utf8RawUrlDecode($formname);

iconv("UTF-8","GB2312",$formname);

因为AJAX通过escape转换数据加密了数据

================================================

查资料显示可以用

$formname=mb_convert_encoding($formname,"GB2312","UTF-8");
