If you want to count quarters between dates you can use the following:
function countQuarters($begindate, $enddate)
{
if (!isset($begindate) || empty($begindate) || !isset($enddate) || empty($enddate))
return -1;
$countyears = date("Y", strtotime($enddate)) - date("Y",
strtotime($begindate));
$quarters = 0;
if (date("Y", strtotime($enddate)) == date("Y", strtotime($begindate)))
{
if (date("m", strtotime($enddate)) != date("m", strtotime($begindate)))
{
if (date("m", strtotime($enddate)) > date("m", strtotime($begindate)))
{
$difference = date("m", strtotime($enddate)) - date("m",
strtotime($begindate));
$quarters += ceil((int) $difference / 4);
}
else
{
return -1;
}
}
}
else
{
$quarters = (int) $countyears * 4;
if (date("m", strtotime($enddate)) != date("m", strtotime($begindate)))
{
if (date("m", strtotime($enddate)) > date("m", strtotime($begindate)))
{
$difference = date("m", strtotime($enddate)) - date("m",
strtotime($begindate));
$quarters += ceil((int) $difference / 4);
}
else
{
$afterbegin = 12 - (int) date("m", strtotime($begindate));
$untilend = date("m", strtotime($enddate));
$quarters = ($quarters - 4) + ceil(($afterbegin + $untilend) / 4);
}
}
}
return $quarters;
}
