[Solved] How to create series of set in PHP [closed]

by


Stylish functional code:

function createSeries($min, $max, $interval, $connector) {
    return array_map(
        function ($num) use ($interval, $connector) {
            return implode(' ', array($num, $connector, $num + $interval));
        },
        range($min, $max - $interval, $interval)
    );
}

However, the most efficient way seems to be:

function createSeries($min, $max, $interval, $connector) {
    $series = array();
    for ($i = $min; $i < $max; $i += $interval) {
        $tail = $i + $interval;
        $series[] = "$i $connector $tail";
    }
    return $series;
}

NOTE: PHP is very slow scripting language. You should not mind efficiency extreamly.
