Question

I have a 2d array in a session variable:

$_session['multi'][] = array('item0 ' , 'price0');
$_session['counter']++;

$_session['multi'][] = array('item1 ' , 'price1');
$_session['counter']++;

I want to be able to show the array (and put them in the database) like this:

$_session['multi'][0][0] , $_session['multi'][0][1]
$_session['multi'][1][0] , $_session['multi'][1][1]
.
.
.

I am using a for loop to do that:

for(){
    show $_session['multi][i][0] , $_session['multi][i][1]
}

But I have to carry a session (counter) with the number of the rows around to use it with the for loop.

Is there any way to get the number of the rows so I can lose the counter?

Answer 1

If you just want the number of items in $_SESSION['multi'] it’s as simple as:

count($_SESSION['multi']);
