UNICODE encoding and decoding in PHP_PHP tutorial

This article is a detailed analysis and introduction to UNICODE encoding and decoding in PHP. Friends who need it can refer to it. ​

Method 1:

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);
}
else
{
$str .= $c2;
}
}
return $str;
}
//Decode the UNICODE encoded content
function unicode_decode($name)
{
//Convert encoding, convert Unicode encoding into browseable utf-8 encoding
$pattern = '/([w]+)|(u([w]{4}))/i';
preg_match_all($pattern, $name, $matches);
if (!empty($matches))
{
$name = '';
for ($j = 0; $j < count($matches[0]); $j++)
{
$str = $matches[0][$j];
if (strpos($str, 'u') === 0)
{
$code = base_convert(substr($str, 2, 2), 16, 10);
$code2 = base_convert(substr($str, 4), 16, 10);
$c = chr($code).chr($code2);
$c = iconv('UCS-2', 'UTF-8', $c);
$name .= $c;
}
else
{
$name .= $str;
}
}
}
return $name;
}

Method 2:

Copy code The code is as follows:

function unicode2utf8($str){
if(!$str) return $str;
$decode = json_decode($str);
if($decode) return $decode;
$str = '["' . $str . '"]';
$decode = json_decode($str);
if(count($decode) == 1){
return $decode[0];
}
return $str;
}
