Pass $end and $start as where conditions and use

Using the date() method can only get the year, month and day of the current time, but when you query from the database The time format cannot be obtained using this method, such as: date("d",$time);
But using date(), you can obtain date("Y",$time), date("M ",$time),date("D",$time), but if we want to get the current date, we can use the split function
twice and that's it!

<?php  
//取得时间的年  
$strtimes=$info[datetime]  
$strtimes = explode(" ",$strtime);  
$timearray = explode("-",$strtimes[0]);  
$year = $timearray[0];  
$month = $timearray[1];  
$day = $timearray[2];  
  
?>
