Generating a list of month names

Am am current facing a problem that need a solution ASAP.

I am trying to list all months of the year by using the following code:

for ($m = 1; $m <= 12; $m++) {
    $month = date('F', mktime(0, 0, 0, $m));
    echo $month . '<br/>';
}

But am getting the following unexpected output:

January
March

I know this is old, but here is a different PHP 7+ DateTime based approach to get an array of month names:

Solution 1

$monthSet = array_map(
    fn (int $m): string => (DateTime::createFromFormat('m-d', "$m-1")->format('F')),
    range(1, 12),
);

Explanation:

  • range() produces an array [1...12]
  • array_map() runs the arrow function on each of these numeric months $m
  • createFromFormat() is passed $m and 1 as the day (otherwise the day defaults to the current day and e.g. Feb-31 would overflow to the next month).

Solution 2

Slightly more verbose, but uses the DatePeriod and DateInterval for their intended purpose (rather than just hardcoding 1-12).

$monthSet = array_map(
    fn(\DateTimeImmutable $dt): string => $dt->format('M'),
    iterator_to_array(new \DatePeriod(
        new \DateTimeImmutable('first day of jan'),
        new \DateInterval('P1M'),
        11,
    )),
);

Explanation:

  • DatePeriod returns an iterator
  • Starting on the first day of the year
  • DateInterval('P1M') sets an interval of 1 month
  • Ending after 11 recurrences (plus the initial one) == 12

not as with mktime but equally powerful

$array = array("January", "February",.....);
for ($m=0; $m<12; $m++) {
     echo $array[$m]. '<br>';
     }

If you use laravel

@for ($x = 1; $x <= 12; $x++)
<option value="{{$x}}">{{date('F', mktime(0, 0, 0, $x, 10))}}</option>
@endfor

Pay attention to the localization.

You can also use this 

setlocale(LC_TIME, 'it_IT');
for($m=1;$m<=12;$m++){
  echo strftime("%B", mktime(0, 0, 0, $m, 12));
}

Changing the parameter on the function setlocale() you can display the localized text.

I guess you should loop it in this manner. 

for($i = 1 ; $i <= 12; $i++)
{
 echo date("F",strtotime(date("Y")."-".$i."-01"));
 echo "<br/>";
}

Or in your case, you want to use mktime()

for($i = 1 ; $i <= 12; $i++)
{
 echo date("F",mktime(0,0,0,$i,1,date("Y")));
 echo "<br/>";
}

Try this:

for ($m=1; $m<=12; $m++) {
     $month = date('F', mktime(0,0,0,$m, 1, date('Y')));
     echo $month. '<br>';
     }

Set day in mktime() to 1, otherwise conversion is performed: 30.2.2012 = 1.3.2012

$month = date('F', mktime(0,0,0,$m,1));
