I used the function as mentioned in the monthly report statistics some time ago. I combined it with others to use the mktime() function and wrote one, but I kept getting errors afterwards, which was very frustrating. I took some time over the weekend to write one for use. I hope it will be useful to some villagers.
PHP code:-------------------------------------------------- ------------------------------------
/*
* Author: Xin Deng
* Function: Implement a function to push down N months from a specified time
* month($ymd,$len) $ymd time, $len pushes out several months
* $ymd =2005-01-01;
*/
function month($ymd=,$len=12){
$month = array();
$lang = $lang."";
if($ymd){//Judge whether the time format is correct
if(!ereg("([0-9]{4})-([0-9]{1,2} )-([0-9]{1,2})",$ymd)){
echo "";
exit;
}
}
if($len){
if(!ereg("[0-9]+",$len)){
echo $lang."";
exit;
}
}
for( $i=0;$i
if($i==0){
$mktime = $ymd?strtotime($ymd ):time();
}
$month[] = date("Y-m",$mktime);//You can design the format you want according to your needs
$day = date("t ",$mktime);
if($i==0)
$reday = date("d",$mktime);
else
$reday = $day;
$ t1 = $mktime;
$mktime=date("Y-m-d",mktime(date("H",$t1),date("i",$t1),date("s",$t1),date ("m",$t1),date("d",$t1)-$reday,date("Y",$t1)));
$mktime =strtotime($mktime);
}
return $month;
}
$month = month();
foreach($month as $key => $v){
echo $v."
";
}
?>

The effect is as follows:

2004-12
2004-11
2004-10
2004-09
2004-08
