The processing method of JS and PHP to URL encoding

  This article mainly introduces JS and PHP to URL encoding processing methods, the need for friends can refer to the following

Solution: Use JS to the URL of the Chinese characters to escape code.     Code as follows: <a href= "onclick=" window.open (' product_list.php?p_sort= ' +escape (' PHP Development Resource Network ')); " >   After clicking the link:    reference: http://127.0.0.1/shop/product_list.php?p_sort=PHP%u5F00%u53D1%u8D44%u6E90% U7f51   generates such an effect that it is obvious that using PHP's UrlDecode () or Base64_decode () is not solvable.     Solutions, write an inverse function in PHP:      Code as follows: function Js_unescape ($str) {        $ret = ' ';         $len = strlen ($STR);         for ($i = 0; $i < $len; $i + +) {                if ( $STR [$i] = = '% ' && $str [$i +1] = = ' U ') {                    &NBSP ;   $val = Hexdec (substr ($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));                         $i + 5;                                   E LSE if ($STR [$i] = = '% ') {                        $ret. = Urld Ecode (substr ($str, $i, 3));                         $i + 2;                                 Else $re T. = $str [$i];        }        return $ret;       Note that the JS code will be automatically converted into UTF-8, so you must encode the conversion to get the correct results, otherwise it will be Chinese garbled. The     code is as follows:Print iconv (' utf-8 ', ' gb2312 ', Js_unescape ($_request[' p_sort '));     To this we have successfully reversed the JS escape code.     In addition, I found a php to implement JS escape code function:    code as follows: function Phpescape ($str) {$sublen =strlen ($STR); Retrunstring= ""; For ($i =0 $i < $sublen $i + +) {if (Ord ($str [$i]) >=127) {$tmpString =bin2hex iconv ("gb2312", "Ucs-2", substr ($STR, $ i,2)));        //$tmpString =substr ($tmpString, 2,2). substr ($tmpString, 0,2); You may want to open this item under window $retrunString . = "%u". $tmpString; $i + +; else {        $retrunString. = "%". Dechex (Ord ($str [$i]));} return $retrunString; }
