I usually store arrays like follow ...
$member="Null".""."Mary".""."Alex"; //and so on...
INSERT INTO db_name (array_1) VALUES ($member);
then we have a field value like Null_Mary_Alex.... in table called db_name
and we can read members from field like follow...
$cc=split("_",$row["array_1"]);
$j=0;
while(empty($cc[$j])!=1)
{
echo ($j+1).$cc[j]."<br>";
$j++;
}
will show...
1.Null
2.Mary
3.Alex
if somebody do this case more easily...
that will be great...
