 if(isDomainAvailible('1st-Web-Page')){
   echo '<iframe src="1st-Web-Page"></iframe>';
 }
 else
 {
   echo '<iframe src="2nd-Web-Page"></iframe>';
 }
 function isDomainAvailible($domain, $timeout ='30') // Change 30 With Your Desired Time To Check First WebPage
 {
  if(!filter_var($domain, FILTER_VALIDATE_URL))
  {
   returnfalse;
  }
  $curlInit = curl_init($domain);
  curl_setopt($curlInit,CURLOPT_CONNECTTIMEOUT,$timeout);
  curl_setopt($curlInit,CURLOPT_HEADER,true);
  curl_setopt($curlInit,CURLOPT_NOBODY,true);
  curl_setopt($curlInit,CURLOPT_RETURNTRANSFER,true);
