PHP calculates the number of months between intervals

PHP calculates the number of months between times

Create a function that calculates the number of months between times:

/*
*function：计算两个日期相隔多少年，多少月，多少天
*param string $date1[格式如：2011-11-5]
*param string $date2[格式如：2012-12-01]
*return array array('年','月','日');
*/
function diffDate($date1,$date2){
if(strtotime($date1)>strtotime($date2)){
$tmp=$date2;
$date2=$date1;
$date1=$tmp;
}
list($Y1,$m1,$d1)=explode('-',$date1);
list($Y2,$m2,$d2)=explode('-',$date2);
$Y=$Y2-$Y1;
$m=$m2-$m1;
$d=$d2-$d1;
if($d<0){
$d+=(int)date(&#39;t&#39;,strtotime("-1 month $date2"));
$m--;
}
if($m<0){
$m+=12;
$y--;
}
// return array(&#39;year&#39;=>$Y,&#39;month&#39;=>$m,&#39;day&#39;=>$d);
return array(&#39;month&#39;=>$Y2 * 12 + $m);
}

Test

echo &#39;<pre class="brush:php;toolbar:false">&#39;;print_r(diffDate(&#39;2014-12-03&#39;,&#39;2000-12-01&#39;));

Result

Array
(
    [month] => 24168
)
