How to handle url encoding in js and php_PHP tutorial

This article mainly introduces how js and php handle url encoding. Friends in need can refer to it

Solution: Use js to escape encode the Chinese characters in the URL.​ ​ The code is as follows: ​ The time after clicking the link is as follows: ​ Quote: http://127.0.0.1/shop/product_list.php?p_sort=PHP%u5F00%u53D1%u8D44%u6E90%u7F51 ​ Such an effect is generated, and it is obvious that it cannot be decoded using PHP's urldecode() or base64_decode().​ ​ Solution, use PHP to write an inverse solution function: ​ The code is as follows: function js_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] == '%'){                                                                                                                                                                                                                                                                         through $ret .= urldecode(substr($str, $i, 3));                                   $i += 2;             }                       else $ret .= $str[$i]; } } Return $ret; } ​ ​ ​ Note that JS encoding will be automatically converted to UTF-8, so the encoding must be converted to get the correct result, otherwise the Chinese characters will be garbled.​ The code is as follows: print iconv('utf-8', 'gb2312', js_unescape($_REQUEST['p_sort'])); ​ ​ At this point we have successfully decoded the escape encoding of js.​ ​ In addition, I found a function that uses PHP to implement escape encoding of js: ​ The code is 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); This may need to be turned on under window $retrunString.="%u".$tmpString; $i++; } else { $retrunString.="%".dechex(ord($str[$i])); }} return $retrunString; }
