字符串转换成unicode unicode_encode


function unicode_encode($name)
{
$name = iconv('UTF-8', 'UCS-2', $name);
$len = strlen($name);

$str = '';
for ($i = 0; $i < $len - 1; $i = $i + 2) { $c = $name[$i]; $c2 = $name[$i + 1]; if (ord($c) > 0)
{ //两个字节的文字
$str .= '\u'.base_convert(ord($c), 10, 16).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT);
}
else
{
$str .= $c2;
}
}
return $str;
