_php tutorial on Unicode encoding and decoding in PHP

This article is a detailed analysis of the Unicode encoding and decoding in PHP, the need for a friend reference

Method One:

Copy CodeThe 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];
$c 2 = $name [$i + 1];
if (ord ($c) > 0)
{//two bytes of text
$str. = ' u '. Base_convert (Ord ($c), ten, 0). Str_pad (Base_convert (Ord ($c 2), ten, 2),, str_pad_left);
}
Else
{
$str. = $c 2;
}
}
return $str;
}
Decoding Unicode-encoded content
function Unicode_decode ($name)
{
Convert encoding to convert Unicode encoding into a utf-8 encoding that can be browsed
$pattern = '/([w]+) | (U ([w]{4}))/I ';
Preg_match_all ($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);
$code 2 = Base_convert (substr ($STR, 4), 16, 10);
$c = Chr ($code). Chr ($code 2);
$c = Iconv (' UCS-2 ', ' UTF-8 ', $c);
$name. = $c;
}
Else
{
$name. = $str;
}
}
}
return $name;
}

Method Two:

Copy CodeThe 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;
}
