php unicode与字符串互转

php字符串转Unicode编码, Unicode编码转php字符

百度了很多,都一样, 要么不对, 要不就是只是把字符串的汉字转Unicode

经过多次试验查找, 找到了如下方法,

注意:字符串编码必须是utf-8,如果不是自行用icon转一下
//字符串转Unicode编码
function unicode_encode($strLong) {
$strArr=pre{g}_{s}plit{(}^{\prime }/(?<{!}^{)}(?!$)/u’, $strLong);//拆分字符串为数组(含中文字符)
$resUnicode{=}^{\prime \prime };foreach($strArr as $str)
{
$bin_str = ‘’;
$arr=i{s}_{a}rray($str) ? $str:st{r}_{s}plit($str);//获取字符内部数组表示,此时$arr应类似array(228,189,160)foreach($arr as $value)
{
$bi{n}_{s}tr.=decbin(ord($value));//转成数字再转成二进制字符串,$bin_str应类似111001001011110110100000,如果是汉字"你"
}
$bi{n}_{s}tr=pre{g}_{r}eplace{(}^{\prime }{/}^{.}4(.4).2(.6).2(.6)$/’, ‘$1$2$3’, $bin_str);//正则截取, $bin_str应类似0100111101100000,如果是汉字"你"
$unicode=dechex(bindec($bin_str));//返回unicode十六进制
${}_{s}up{=}^{\prime \prime };for($i = 0; $i<4-strlen($unicode); $i++)
{
$_sup .= ‘0’;//补位高字节 0
}
$str = ‘\u’ . $_sup . $unicode; //加上 \u 返回
$resUnicode .= $str;
}
return KaTeX parse error: Expected 'EOF', got '}' at position 13: resUnicode; }̲ //Unicode编码转字符…name)
{
// 转换编码，将Unicode编码转换成可以浏览的utf-8编码
KaTeX parse error: Undefined control sequence: \w at position 15: pattern = '/([\̲w̲]+)|(\\\u([\w]{…pattern, $name, $matches);if(!empty($matches))
{
$name{=}^{\prime \prime };for($j = 0; $j<count($matches[0]); $j++)
{
$str = $matches[0][$j];
if (strpos($str, ‘\u’) === 0)
{
$code=bas{e}_{c}onvert(substr($str, 2, 2), 16, 10);
$code2=bas{e}_{c}onvert(substr($str, 4), 16, 10);
$c=chr($code).chr($code2);
$c = iconv(‘UCS-2’, ‘UTF-8’, $c);
$name .= $c;
}
else
{
$name .= $str;
}
}
}
return KaTeX parse error: Expected 'EOF', got '}' at position 7: name; }̲ //Unicode编码转字符…str){
$json = ‘{“str”:"’ . $str . ‘"}’;
$arr=jso{n}_{d}ecode($json, true);
if (empty($arr)) return ‘’;
return $arr[‘str’];
}

echo unicode_encode(‘若水小站:qq963087326’),’
’;
//结果\u82e5\u6c34\u5c0f\u7ad9\u003a\u0071\u0071\u0039\u0036\u0033\u0030\u0038\u0037\u0033\u0032\u0036

echo unicode_decode(’\u82e5\u6c34\u5c0f\u7ad9\u003a\u0071\u0071\u0039\u0036\u0033\u0030\u0038\u0037\u0033\u0032\u0036’);
