Looping through array and output as pairs (divider for each second element)

Question

I have an array with anonymous elements. Elements are added to the array via php, like so:

$playlist = array();

while (databaseloop) {
  $playlist[] = $a_ti         


        

Answer 1

Well, maybe this is the most basic solution:

for (var i = 0; i < arr.length; i += 2) {
    var title = arr[i];
    var len = arr[i+1];
}

However, I would recommend you to arrange $playlist as follows:

while (databaseloop) {
    $playlist[] = array(
        "title" => $a_title,
        "length" => $a_length
    );
}

Then it will be easy to iterate the elements simply with:

for (var i = 0; i < arr.length; i++) {
    var title = arr[i]['title'];
    var len = arr[i]['length'];
}
