js的escape轉義中文php的轉換函式_PHP教程

很多時候需要用到js的escape函數來轉換中文字元，可是用js轉換後的字元怎麼用php來轉換回來呢，下面我就找到了兩個很實用的函數。

GB2312編碼：

代碼如下

function unescape($str) { $str = rawurldecode($str); preg_match_all("/%u.{4}|&#x.{4};|&#d+;|.+/U",$str,$r); $ar = $r[0]; foreach($ar as $k=>$v) { if(substr($v,0,2) == "%u") $ar[$k] = iconv("UCS-2","GBK",pack("H4",substr($v,-4))); elseif(substr($v,0,3) == "&#x") $ar[$k] = iconv("UCS-2","GBK",pack("H4",substr($v,3,-1))); elseif(substr($v,0,2) == "&#") { $ar[$k] = iconv("UCS-2","GBK",pack("n",substr($v,2,-1))); } } return join("",$ar); }

UTF8編碼：

function unescape($str){ $ret = ''; $len = strlen($str); for ($i = 0; $i < $len; $i++){ if ($str[$i] == '%' && $str[$i+1] == 'u'){ $val = hexdec(substr($str, $i+2, 4)); if ($val < 0x7f) $ret .= chr($val); else if($val < 0x800) $ret .= chr(0xc0|($val>>6)).chr(0x80|($val&0x3f)); else $ret .= chr(0xe0|($val>>12)).chr(0x80|(($val>>6)&0x3f)).chr(0x80|($val&0x3f)); $i += 5; } else if ($str[$i] == '%'){ $ret .= urldecode(substr($str, $i, 3)); $i += 2; } else $ret .= $str[$i]; } return $ret; }
