php转换unicode编码的方法:首先创建一个PHP示例文件;然后通过“unicode_encode”方法将字符串转Unicode编码;最后使用“unicode_decode”方法将Unicode编码转字符串即可。

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) { $strArr = preg_split('/(?<!^)(?!$)/u', $strLong);//拆分字符串为数组(含中文字符) $resUnicode = ''; foreach ($strArr as $str) { $bin_str = ''; $arr = is_array($str) ? $str : str_split($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) { $bin_str .= decbin(ord($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" } $bin_str = preg_replace('/^.{4}(.{4}).{2}(.{6}).{2}(.{6})$/', '$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 $_sup = ''; for ($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 $resUnicode; } //Unicode编码转字符串方法1 function unicode_decode($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 $name; } //Unicode编码转字符串 function unicode_decode2($str){ $json = '{"str":"' . $str . '"}'; $arr = json_decode($json, true); if (empty($arr)) return ''; return $arr['str']; } echo unicode_encode('若水小站:qq963087326'),'<br>'; //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'); //结果若水小站:qq963087326
