in every webpage request you can set increment of query string which indicate which index we need to print on this web call..
like
arrayoverflow.com/webcall.php?request=1
arrayoverflow.com/webcall.php?request=2
arrayoverflow.com/webcall.php?request=3


if(isset($_REQUEST['request']) && $_REQUEST['request']!=''){
$request=array('first request',"second request","third request");
if(isset($request[$_REQUEST['request']])){
echo $request[$_REQUEST['request']];   
}
}

so you can pass index at query parameters

but it should be auto remember . i dont want to pass the index as query string - jaydeep

why you dont use the session to remember which one index is need to print


$ARRAY=array("my","name","is","rasila");
session_start();
if(!isset($_SESSION['index']) )
$_SESSION['index']=0;
if($_SESSION['index']>count($array) )
$_SESSION['index']=0;

echo $ARRAY[$_SESSION['index']];
$_SESSION['index']=$_SESSION['index']+1;

above code print each time next indexed array value . if it reach at end of array than it reset automatically and start from first index again to print

and if you dont have issue with COOKIE than you can use PHP COOKIE also
same code will be look like this in PHP


$ARRAY=array("my","name","is","rasila");
 if(!isset($_COOKIE['index']) )
set_cookie('index',0,time()+3600);
if($_COOKIE['index']>count($array) )
$_COOKIE['index']=0;

echo $ARRAY[$_COOKIE['index']];
$_COOKIE['index']=$_COOKIE['index']+1;
