JS代码转成PHP代码,该如何处理

JS代码转成PHP代码

<script type="text/javascript"><br />function rightSide(playerID) {<br />    this.Decrypt2 = function(data) {<br />        var b = (7 * (data - 6) % 10 + 10) % 10;<br />        return b.toString();<br />		alert(b.toString());<br />    }<br /><br />    this.Decrypt = function(playerID) {<br />        playerID = playerID.toString();<br />        var arrID = new Array();<br />        for (var i = 0; i < playerID.length; i = i + 1) {<br />            var a = playerID.substr(i, 1);<br /><br />            switch (a) {<br />                case "0": arrID.push(this.Decrypt2(0)); break;<br />                case "4": arrID.push(this.Decrypt2(1)); break;<br />                case "5": arrID.push(this.Decrypt2(2)); break;<br />                case "3": arrID.push(this.Decrypt2(3)); break;<br />                case "6": arrID.push(this.Decrypt2(4)); break;<br />                case "9": arrID.push(this.Decrypt2(5)); break;<br />                case "7": arrID.push(this.Decrypt2(6)); break;<br />                case "1": arrID.push(this.Decrypt2(7)); break;<br />                case "2": arrID.push(this.Decrypt2(8)); break;<br />                case "8": arrID.push(this.Decrypt2(9)); break;<br />            }<br />        }<br />        return arrID.join('');<br />    }<br />	return this.Decrypt(playerID);<br />}	<br />var idArr = rightSide(5705);

以上JS代码，帮忙转成PHP代码，谢谢各位了！！！

按 php 闭包直译（需 >= php 5.3）

function rightSide($playerID) {<br>    $Decrypt2 = function($data) {<br>        $b = (7 * ($data - 6) % 10 + 10) % 10;<br>        return $b;<br>    };<br> <br>    $Decrypt = function($playerID) use ($Decrypt2) {<br>        $playerID = "$playerID";<br>        $arrID = Array();<br>        for ($i = 0; $i             $a = substr($playerID, $i, 1);<br> <br>            switch ($a) {<br>                case "0": $arrID[] = $Decrypt2(0); break;<br>                case "4": $arrID[] = $Decrypt2(1); break;<br>                case "5": $arrID[] = $Decrypt2(2); break;<br>                case "3": $arrID[] = $Decrypt2(3); break;<br>                case "6": $arrID[] = $Decrypt2(4); break;<br>                case "9": $arrID[] = $Decrypt2(5); break;<br>                case "7": $arrID[] = $Decrypt2(6); break;<br>                case "1": $arrID[] = $Decrypt2(7); break;<div class="clear">
