PHP怎样计算两个日期相差几个月？
<br />
<?php<br />
function getMonthNum( $date1, $date2, $tags='-' ){<br />
$date1 = explode($tags,$date1);<br />
$date2 = explode($tags,$date2);<br />
return abs($date1[0] - $date2[0]) * 12 + abs($date1[1] - $date2[1]);<br />
}<br />
<br />
echo getMonthNum("2013-02-01","2014-01-01",'-');<br />
<br />
?><br />
