[Peeyush]

But problem is how can i make my program read page's source code?

you could load your example.php's in an iframe.
<iframe id="Tester" onload="Test();">

var Currentpage=1;
var MaxPage=1000;
var HitPages=[];
function Test(){
TestFrame=document.getElementById('Tester');
Content=TestFrame.contentDocument.body.innerHTML;
isMatch=Content.match(/hello/);
if (isMatch){
HitPages.push(CurrentPage);
}
CurrentPage++;
if (CurrentPage <= MaxPage){
TestFrame.src="example.com/example.php?page="+CurrentPage;
}else{
  // code for handling the result (HitPages)
}
}
window.onload=function(){document.getElementById('Tester').src="example.com/example.php?page="+CurrentPage;}
