PHP strtotime giving the wrong date for certain months

the following code.

strtotime("first saturday", strtotime("+2 month"));

Is working correctly but with the months of April +2 month, October + 8 month, and December + 10 month is giving the second saturday in that month not the first.

Any ideas what is causing it and how to stop it.

Marvellous

This is because "first saturday" is calculate from the date given. If given date already is a saturday, the next one is calculated.

If you need the first saturday from a specific month, do:

$stamp = time();
$tm = localtime($stamp, TRUE);

// +1 to account for the offset, +2 for "+2 month"
$begin = mktime(0, 0, 0, $tm['tm_mon'] + 1 + 2, 1, 1900 + $tm['tm_year']);

if (6 == $begin['tm_wday']) {
//  we already got the saturday
    $first_saturday = $stamp;
} else {
    $first_saturday = strtotime('first saturday', $begin);
}

Use the first day of the month to create your origin timestamp, and then just check the month/year:

function firstSaturday($month, $year) {
    if (!is_numeric($month) && !is_numeric($year)) {
        return -1;
    }

    return strtotime('first saturday', mktime(0, 0, 0, $month, 1, $year));
}
