PHP makes unicode decoding tool (unicode encoding converter) code sharing_PHP tutorial

Copy code The code is as follows:

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)
{ //Two bytes of text
$str .= 'u'.base_convert(ord($c), 10, 16).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT);
                                                                                                                                                            . }
}
return $str;
}

//Decode the UNICODE encoded content
function unicode_decode($name)
{ //Convert the encoding, convert the Unicode encoding into a browseable utf-8 encoding

$ pattern = '/([w]+)|(\u([w]{4}))/i';
preg_match_all($pattern, $name, $matches);
