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

A simple for loop with an increment of two. You might want to make sure that your array length is long enough for i+1, in case the length isn't divisible by 2!

for (i = 0; i+1 < array.length; i+=2) {
  name = array[i];
  length = array[i+1];
}
