Custom function gone crazy.

[AmenKa]

I am sure I have made a relatively stupid error, a helping hand would be great!

My code:

<?php
// Returns an acurate number of seconds in the current month.
function months_seconds() {
if(date(n) = 1) { // January.
  $jan = date(n) * 31 * 24 * 60 * 60;
  return($jan);
} elseif(date(n) = 2) { // February.
  if(date(L) = 1) { // Leap year.
    $lfeb = date(n) * 29 * 24 * 60 * 60;
    return($lfeb);
  } elseif(date(L) = 0) { // No leap year.
    $nfeb = date(n) * 28 * 24 * 60 * 60;
    return($nfeb);
  }
} elseif(date(n) = 3) { // March.
  $mar = date(n) * 31 * 24 * 60 * 60;
  return($mar);
} elseif(date(n) = 4) { // April.
  $apr = date(n) * 30 * 24 * 60 * 60;
  return($apr);
} elseif(date(n) = 5) { // May.
  $may = date(n) * 31 * 24 * 60 * 60;
  return($may);
} elseif(date(n) = 6) { // June.
  $jun = date(n) * 30 * 24 * 60 * 60;
  return($jun);
} elseif(date(n) = 7) { // July.
  $jul = date(n) * 31 * 24 * 60 * 60;
  return($jul);
} elseif(date(n) = 8) { // August.
  $aug = date(n) * 31 * 24 * 60 * 60;
  return($aug);
} elseif(date(n) = 9) { // September.
  $sep = date(n) * 30 * 24 * 60 * 60;
  return($sep);
} elseif(date(n) = 10) { //October.
  $oct = date(n) * 31 * 24 * 60 * 60;
  return($oct);
} elseif(date(n) = 11) { // November.
  $nov = date(n) * 30 * 24 * 60 * 60;
  return($nov);
} elseif(date(n) = 12) { // December.
  $dec = date(n) * 31 * 24 * 60 * 60;
  return($dec);
}
}
echo(months_seconds());
?>

The error: "Fatal error: Can't use function return value in write context in /home/shadowte/public_html/months_seconds.php on line 4"

This simple function gets the month of the year, then converts that into seconds.

As I said, im sure I have made some stupid error in my attempt to simplify the process of getting the current month's number of seconds. Any help would be greatly appreciated.

not sure if this will help you out on your error but you should probably change all of your "=" in your ifs and else ifs to "=="...

We have a winner! Thank you! Funny how those stupid little things kill you when you aren't sharp.

*puts a define('L', 2500) at the top of your script and watches the function break*

By default, PHP will convert undefined constants like L and n in that script to strings. However. you must never, ever rely upon this. Put them in quotes.

That's one redundant function. It can be better written so:

function seconds_in_month($time = false) {
  if ($time === false)
    $time = time();

  list($y, $m) = explode('-', date('Y-m', $time));
  return strtotime(sprintf('%s-%s-01', $y, $m + 1)) - strtotime(sprintf('%s-%s-01', $y, $m));
}

Lol I wasn't sure if that was gonna fix your problem but I'm glad it did!

}

I was actually wondering yesterday if that mattered, good to have it cleared up.
