Just thought I would like to share this should someone find a use for it.
Basically I needed a list of HTML colors to loop / cycle through. So I need to remove the first element of the array, place it at the end and then get the current HTML color.
Given the following array:
$colors = array(
"#2265fa", "#b61d1e", "#53b822", "#a9d81c", "#d6e9f5", "#43cc7d", "#e3159a",
"#80c85e", "#17b303", "#989240", "#014c07", "#d265f3", "#22bbb9", "#6c69a9",
"#7ea13a", "#0dcea2", "#99c27d", "#41405b", "#731801"
);
