辅助类 UnicodeHelper : Unicode编码转换

  • static string2Unicode8($string, $type = NumberHelper::TYPE_HEX) : 将字符串转换成utf-8的进制编码
  • static unicode82String($code, $type = NumberHelper::TYPE_HEX) : 将utf-8的进制编码转换成字符串
  • static char2Unicode($char, $length = 0) : unicode码转换成utf-8字符
  • static unicode2Char($unicode) : 将字符串转换成utf-8的进制编码
  • static string2Unicode($string, $type = NumberHelper::TYPE_HEX, $unicodeByte = 4) : 将字符串转换成unicode的进制编码
  • static unicode2String($code, $type = NumberHelper::TYPE_HEX, $unicodeByte = 4) : 将unicode的进制编码转换成字符串

unicode 编码介绍

Utf-8字符编码转换成Unicode参考下面列表，将"x"从后向前排列，位数补足8的倍数(前位补0)

Unicode 编码范围 Utf-8 表示 Unicode 字节表示
U-00000000 - U-0000007F 0xxxxxxx 1*0 + 1u
U-00000080 - U-000007FF 110xxxxx 10xxxxxx 5*0 + 2u
U-00000800 - U-0000FFFF 1110xxxx 10xxxxxx 10xxxxxx 0*0 + 2u
U-00010000 - U-001FFFFF 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 3*0 + 3u
U-00200000 - U-03FFFFFF 111110xx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 6*0 + 4u
U-04000000 - U-7FFFFFFF 1111110x 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 10xxxxxx 1*0 + 4u

test 代码

$string = 'phpcorner Php小刀';
var_dump("====== utf-8编码转换 ======");
// 十六进制
var_dump("十六进制");
$code = UnicodeHelper::string2Unicode8($string);
var_dump($code);
$newString = UnicodeHelper::unicode82String($code);
var_dump($newString);

// 二进制
var_dump("二进制");
$code = UnicodeHelper::string2Unicode8($string, NumberHelper::TYPE_BINARY);
var_dump($code);
$newString = UnicodeHelper::unicode82String($code, NumberHelper::TYPE_BINARY);
var_dump($newString);

// 八进制
var_dump("八进制");
$code = UnicodeHelper::string2Unicode8($string, NumberHelper::TYPE_OCTAL);
var_dump($code);
$newString = UnicodeHelper::unicode82String($code, NumberHelper::TYPE_OCTAL);
var_dump($newString);

// 64进制
var_dump("64进制");
$code = UnicodeHelper::string2Unicode8($string, NumberHelper::TYPE_BASE64);
var_dump($code);
$newString = UnicodeHelper::unicode82String($code, NumberHelper::TYPE_BASE64);
var_dump($newString);

$char = '在';
var_dump("====== 字符编码转换 ======");
var_dump("字符转化");
$code = UnicodeHelper::char2Unicode($char, 4);
var_dump($code);
$newChar = UnicodeHelper::unicode2Char($code);
var_dump($newChar);

$string = 'phpcorner Php小刀';
var_dump("====== unicode编码转换 ======");
// 十六进制
var_dump('十六进制');
$code = UnicodeHelper::string2Unicode($string);
var_dump($code);
$newString = UnicodeHelper::unicode2String($code);
var_dump($newString);

// 二进制
var_dump('二进制');
$code = UnicodeHelper::string2Unicode($string, NumberHelper::TYPE_BINARY);

var_dump(NumberHelper::binaryToHex($code));
var_dump($code);
$newString = UnicodeHelper::unicode2String($code, NumberHelper::TYPE_BINARY);
var_dump($newString);

// 八进制
var_dump('八进制');
$code = UnicodeHelper::string2Unicode($string, NumberHelper::TYPE_OCTAL);
var_dump($code);
var_dump(NumberHelper::octalToHex($code));
$newString = UnicodeHelper::unicode2String($code, NumberHelper::TYPE_OCTAL);
var_dump($newString);

// 64进制
var_dump('64进制');
$code = UnicodeHelper::string2Unicode($string, NumberHelper::TYPE_BASE64);
var_dump($code);
var_dump(NumberHelper::base64ToHex($code));
$newString = UnicodeHelper::unicode2String($code, NumberHelper::TYPE_BASE64);
var_dump($newString);
