本文给大家分享一个PHP解密Unicode及Escape加密字符串函数
<?php function uni_decode($s) { preg_match_all('/\&\#([0-9]{2,5})\;/', $s, $html_uni); preg_match_all('/[\\\%]u([0-9a-f]{4})/ie', $s, $js_uni); $source = array_merge($html_uni[0], $js_uni[0]); $js = array(); for($i=0;$i>6); $str.=chr(0x80 | $c & 0x3f); } else if ($c < 0x10000) { $str.=chr(0xe0 | $c>>12); $str.=chr(0x80 | $c>>6 & 0x3f); $str.=chr(0x80 | $c & 0x3f); } else if ($c < 0x200000) { $str.=chr(0xf0 | $c>>18); $str.=chr(0x80 | $c>>12 & 0x3f); $str.=chr(0x80 | $c>>6 & 0x3f); $str.=chr(0x80 | $c & 0x3f); } return $str; } $str='%u5927%u5BB6%u597D%uFF0C我是孤魂!
\u8FD9\u662F\u6D4B\u8BD5\u6587\u672C\uFF01'; echo uni_decode($str); // 大家好,我是孤魂!这是测试文本!
在网上搜索一把,很多用php实现的escape函数,大同小异
function phpescape($str){ preg_match_all("/[\x80-\xff].|[\x01-\x7f]+/",$str,$newstr); $ar = $newstr[0]; foreach($ar as $k=>$v){ if(ord($ar[$k])>=127){ $tmpString=bin2hex(iconv("GBK","ucs-2",$v)); if (!eregi("WIN",PHP_OS)){ $tmpString = substr($tmpString,2,2).substr($tmpString,0,2); } $reString.="%u".$tmpString; } else { $reString.= rawurlencode($v); } } return $reString; }
以上所述就是本文的全部内容了,希望大家能够喜欢。
