PHP计算二个日期之间的月的跨度数（经历的月数）的函数

php
function dateMonthDiff($d1,$d2)
{

$m1 = date("n",strtotime($d1));
$m2 = date("n",strtotime($d2));

$y1 = date("Y",strtotime($d1));
$y2 = date("Y",strtotime($d2));


$a = ($y2-$y1)*12+($m2-$m1)+1;
return $a;
}

//example
$d1 = "2006-1-10";
$d2 = "2006-3-1";

echo dateMonthDiff($d1,$d2);
?>
