_SESSION & associative arrays

[Anon]

Could someone provide a sample syntax for appending an associative array as a _SESSION superglobal?

as a start,

$_SESSION['formVars'] = array('a'=>1,'b'=>2);

foreach($_SESSION["formVars"] as $key=>$value) {
echo "The value of index $key is $value<br />";
}

Now how do I append or access a particular member?

TIA

You can use the serialize and unserialize functions to get your result.
