Check Date Between Two Dates in PHP

function dateBetween( $checkDate )
{
$firstDate1 = strtotime( "15-Jan-2008" );
$firstDate2 = strtotime( "15-Mar-2008" );
$secondDate1 = strtotime( "16-Mar-2008" );
$secondDate2 = strtotime( "15-Jun-2008" );

$checkDate = strtotime( $checkDate );

if( $checkDate > $firstDate1 && $checkDate < $firstDate2 )
{
return "2000";
}
elseif( $checkDate > $secondDate1 && $checkDate < $secondDate2 )
{
return "4000";
}

return "0";

How to calculate the date difference between 2 dates using php

$date1 = "2006-03-25";
$date2 = "2009-11-10";

$diff = abs(strtotime($date2) - strtotime($date1));

$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));

printf("%d years, %d months, %d days\n", $years, $months, $days);
