如何配置IIS既可以运行ASP又可以运行PHP

以下为引用的内容：

<script type="text/javascript">
function bdmp3Url(){
this.I=[];
this.E=[];
this.init();
}
bdmp3Url.prototype = {
init:function(){
this.getkeys(0,9,48);
this.getkeys(10,35,55);
this.getkeys(36,61,61);
},
getkeys:function(Q,N,O){
for(var P=Q;P<=N;P++){
this.I[P]=String.fromCharCode(P+O);this.E[P+O]=P;
}
},
code:function(C,D,F){
//偏移量
var K=D%26;K=K?K:1;K=C?K:-K;

var N=F.length,I=this.I,E=this.E,R='',Q='';

for(var P=0;P<N;P++){
R=F.charAt(P);
if(/[A-Za-z0-9]/.test(R)){
var S=E[F.charCodeAt(P)]+K;
if(C){
if(S>61){S-=62;}
}else{
if(S<0){S+=62;}
}
R=I[S];
}
Q+=R;
}
return Q;
}
}

var x = new bdmp3Url();

document.write(x.code(1,1227148832,'https://www.wzms.net/UploadFiles/2007-1/115747297.wma')+'<br/>');

document.write(x.code(0,1227148832,'iuuq://xxx.x0nt.ofu/VqmpbeGjmft/3118-2/2268583A8.xnb'));
