[PHP] array_push

[Edward Peloke]

Ok,
 
I am having a brain cramp for some reason but I need to pass in an array
to my form class to build select boxes.  The array is ("id"=>"John
Doe"), I need to dynamically build this array from a query but I am
getting errors using array_push.do I need to use array_merge?  Example:
 
$sql=new Database();
$sql->query("select fname,lname, id from clients");
$clients[]=array();
while($sql->nextRecord()){
   array_push($clients, $sql->getField('id')=>$sql->getField('fname'));
 } // while
 
Parse error: parse error, unexpected T_DOUBLE_ARROW in
C:\obox\Apache2\htdocs\nh_vacdest\admin\test.php on line 38
 
How can I dynamically create my array?
 
Thanks,
Eddie
