描述

string rawurldecode ( string str )

返回字符串，此字符串中百分号（%）后跟两位十六进制数的序列都将被替换成原义字符。

例子 1. rawurldecode() 示例

This function also decodes utf8 strings so it behaves more like the javascript unscape() function.



<?php



function utf8RawUrlDecode ($source) {

    $decodedStr = "";

    $pos = 0;

    $len = strlen ($source);

    while ($pos < $len) {

        $charAt = substr ($source, $pos, 1);

        if ($charAt == '%') {

            $pos++;

            $charAt = substr ($source, $pos, 1);

            if ($charAt == 'u') {

                // we got a unicode character

                $pos++;

                $unicodeHexVal = substr ($source, $pos, 4);

                $unicode = hexdec ($unicodeHexVal);

                $entity = "&#". $unicode . ';';

                $decodedStr .= utf8_encode ($entity);

                $pos += 4;

            }

            else {

                // we have an escaped ascii character

                $hexVal = substr ($source, $pos, 2);

                $decodedStr .= chr (hexdec ($hexVal));

                $pos += 2;

            }

        } else {

            $decodedStr .= $charAt;

            $pos++;

        }

    }

    return $decodedStr;

}



?>

To sum it up: the only difference of this function to the urldecode function is that the "+" character won't get translated.
