Javascript to PHP Function

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++){ [login to view URL](0);[login to view URL](0); } for(var n=0;n<10;n++){ [login to view URL](0);[login to view URL](0);[login to view URL](0); } var x=function(zb){ var ze=[login to view URL] Date().getTime():[login to view URL]; var zc=[login to view URL]:[login to view URL];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[[login to view URL](zd\/20)]++; } else if(zd<1000){ r[[login to view URL]((zd-400)\/60)]++; } else if(zd<3000)q[[login to view URL]((zd-1000)\/200)]++; } p=ze; }; var y=function(zc){ var ze=[login to view URL] Date().getTime():[login to view URL]; var zd=[login to view URL]:[login to view URL]; var zb=ze-o[zd%128];if(zb>=50&&zb<250)k[[login to view URL]((zb-50)\/20)]++; }; var v=function(zb){ var zd=[login to view URL](Math,zb); var zc=[];[login to view URL](function(ze){ [login to view URL]([login to view URL](ze*64\/(zd||1))); } ); return zc; }; var l=function(){ var zb=[login to view URL](r,q);return v(zb).concat(v(k),[t\/2,w\/2,za\/2,z\/2]); }; this.getData=function(){ return [login to view URL](l()); }; [login to view URL](u,{keyup:[login to view URL](this),keydown:[login to view URL](this) } ); } function startFormTypeABTester(a){ a.ab_tester=new FormTypeABTester(document); } function setFormTypeABTest(a){ a.ab_test_data.value=[login to view URL]();return true; } </script>
