Answer 1

It is cleary written here that last parameter is_dst of mktime has been removed in PHP 7, You have to give 6 parameters instead of 7.

Try this code snippet here 7.0.8

<?php

ini_set('display_errors', 1);
$month_options = "";
for ($i = 1; $i <= 12; $i++)
{
    $month_num = str_pad($i, 2, 0, STR_PAD_LEFT);
    $month_name = date('F', mktime(0, 0, 0, $i + 1, 0, 0));
    $selected = "";
    $month_options .= $month_name . "<br/>";
}
echo $month_options;

Answer 2

Why not use DateTime objects instead? They are easier to work with, and easier to manipulate. DateTime is available from PHP5.2 and upwards.

This snippet

$date = new DateTime("january");
for ($i = 1; $i <= 12; $i++) {
    echo $date->format("F")."\n";
    $date->modify("+1 months");
}

would output

January
February
March
April
May
June
July
August
September
October
November
December
