Description:
------------
---
From manual page: http://www.php.net/function.preg-grep
---


Test script:
---------------
$var = ucfirst ($_REQUEST['queryString']);
$friends_inner=$_SESSION['friends'];
for($i=0; $i<sizeof($friends_inner); $i++)
{
$selected_friend=$friends_inner[$i];
$selected_friend_id=$selected_friend['id']; //array of ids
$selected_friend_name=$selected_friend['name']; // array of names
$name[$i]=$selected_friend_name;
}
$result=preg_grep('/^'.$var.'.*/', $name);
(to be note)
this will show different result
echo "total elements in matched array name = ".count($result)."<br>";

$final_result=array();
$maxindex = array_pop(array_keys($result));
for($i=0;$i<=$maxindex;$i++){                 //returns array that start with zero
	if(isset($result[$i])){
	array_push($final_result,$result[$i]);
		          }
		 }
$ids_of_result=array();	
function sort_arrays($final_result,$friends_inner) {
	$ids_of_result = array();
	foreach($final_result as $fnl_rslt){
		foreach($friends_inner as $frnd_in){
			if($fnl_rslt == $frnd_in['name']){
				//echo 'Name : '.$frnd_in['name'].'<br>';
				//echo 'Id : '.$frnd_in['id'].'<br>';
				array_push($ids_of_result,$frnd_in['id']); 
			}
		}
	}
	return $ids_of_result;
}
$ids_of_result = sort_arrays($final_result,$friends_inner);	
(to be note)
this will  show different result
echo "total elements in match array ids =  ".count($ids_of_result)."<br>";

Can you provide a cleaner example, showing the data you are using and the expected 
and actual results please? Your test script is specific to your requirements and 
your data.

It's been two months now. I don't think we're going to get the feedback we need. 
If feedback is provided, reopen the bug.
