Project Description:
I require the following function to be changed into PHP if it is possible so that I can generate the same results in PHP that this javascript runs.
Code:
<script>
function FormTypeABTester(u){
var g=16;
var h=32;
var a=65;
var i=90;
var j=48;
var b=57;
var c=58;
var d=63;
var e=91;
var f=94;
var t=0;
var w=0;
var za=0;
var z=0;
var o=[];
var p=null;
var k=[];
var s=[];
var r=[];
var q=[];
for(var m=0;m<10;m++){
k.push(0);s.push(0);
}
for(var n=0;n<10;n++){
s.push(0);r.push(0);q.push(0);
}
var x=function(zb){
var ze=window.event?new Date().getTime():zb.timeStamp;
var zc=window.event?window.event.keyCode:zb.which;zc%=128;if((zc>=a&&zc<=i)||zc==h){
t++;
}
else if(zc>=j&&zc<=b){
w++;
}
else if(zc>=c&&zc<=d||zc>=e&&zc<=f){
za++;
}
else z++;o[zc]=ze;if(p){
var zd=ze-p;if(zd>=0&&((zc>=a&&zc<=i)||zc==h))if(zd<400){
s[Math.floor(zd\/20)]++;
}
else if(zd<1000){
r[Math.floor((zd-400)\/60)]++;
}
else if(zd<3000)q[Math.floor((zd-1000)\/200)]++;
}
p=ze;
};
var y=function(zc){
var ze=window.event?new Date().getTime():zc.timeStamp;
var zd=window.event?window.event.keyCode:zc.which;
var zb=ze-o[zd%128];if(zb>=50&&zb<250)k[Math.floor((zb-50)\/20)]++;
};
var v=function(zb){
var zd=Math.max.apply(Math,zb);
var zc=[];zb.each(function(ze){
zc.push(Math.floor(ze*64\/(zd||1)));
}
);
return zc;
};
var l=function(){
var zb=s.concat(r,q);return v(zb).concat(v(k),[t\/2,w\/2,za\/2,z\/2]);
};
this.getData=function(){
return Base64.encodeNums(l());
};
Event.listen(u,{keyup:y.bind(this),keydown:x.bind(this)
}
);
}
function startFormTypeABTester(a){
a.ab_tester=new FormTypeABTester(document);
}
function setFormTypeABTest(a){
a.ab_test_data.value=a.ab_tester.getData();return true;
}
</script>
