复制代码 代码如下:

<?php

function unicode_encode($name)

{

$name = iconv('UTF-8', 'UCS-2', $name);

$len = strlen($name);

$str = '';

for ($i = 0; $i < $len - 1; $i = $i + 2)

{

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;

}

//将UNICODE编码后的内容进行解码

function unicode_decode($name)

{

//转换编码，将Unicode编码转换成可以浏览的utf-8编码

$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;

}
