Question

What is the proper way to add an array to a $_SESSION variable that already contains arrays in PHP?

For example I have a session variable:

$_SESSION['test']

Then I do this:

$_SESSION['test'] = array('sample' => '1', 'sample2' => 2);

THEN, I come back to this session data at a later date. How would I add another array to $_SESSION[‘test’] without destroying what was already in there?

Answer 1

Fetch the size of current value, if it’s 1 (means there is one array), then make a new array, which contains previous value from test and add the new value. Then change test value to this new two dimension array.

Would look something like that:

$_SESSION['test'] = array('sample' => '1', 'sample2' => 2);

if(is_array($_SESSION['test']) && sizeof($_SESSION['test'] == 1){
    $newValue = array();
    $newValue[] = $_SESSION['test'];
    $newValue[] = $yourOtherArray;
    $_SESSION['test'] = $newValue;
}

Fast and simple. Oh, not so sure if this is “proper” way.
