How to echo 1st and 15th of the month in php [closed]

Answer 1

My solution, with DateTime objects: Seems much simpler, doesn't it?

<?php

header("Content-type: text/plain");

$date = new DateTime("2012-01-01");
echo $date->format("Y-m-d"), PHP_EOL;
$date->modify("+14 days");
echo $date->format("Y-m-d"), PHP_EOL;

while ($date->format("Y") != "2013") {
    $date->modify("first day of next month");
    echo $date->format("Y-m-d"), PHP_EOL;
    $date->modify("+14 days");
    echo $date->format("Y-m-d"), PHP_EOL;
}
