No of months between two timestamps (Unix timestamps)

[nadeemshafi9]

How can I get the enlapsed months, complete months between two timestamps (Unix timestamps)? is there any function that'll help me ? or what aproach should I use?

Except for simple comparisons, timestamps must be converted to be usable for most purposes. Because the number of days in the months are not constant, you would need to convert to years, months, days and do the math.

 

I would take the difference in the years * 12, plus the difference in the months (subtract 1 if the end day is less-than the start day.)

 

Untested, but should work -

 

<?php
// whole months 

// get the timestamps into year, month, day values using your preferred method -
$start = '2008-07-29';
$end = '2009-08-29';

list($sy,$sm,$sd) = explode("-",$start);
list($ey,$em,$ed) = explode("-",$end);

$months = (($ey-$sy) * 12) + ($em - $sm) - ($ed < $sd);
echo $months;
?>
