Use An Array Recursively

Let's say that you have a dynamic list with items coming in from a database. For each item in the list, you want the background colour to be different.

Firstly, create an array of colours.

$colours = array('#505d6a', '#832b67', '#612b83', '#2b3f83', '#2b8367', '#0096b6', '#1fa400', '#ff7e00', '#990000', '#707d00');

Then, to loop through each item and assign the next colour in the array AND THEN start the colours from the beginning again if there are more items than colours:

$i = 0;

// Lets assume my items are stored in an array called $items
foreach($items as $item) {
    echo "<div style='background:".$colours[ ($i % count($colours)) ].";'>";
    echo $item;
    echo "</div>";
