PHP method to obtain the timestamps of the current month and the beginning and end of the previous month

This article mainly introduces the method of PHP to obtain the timestamps of the current month and the beginning and end of the previous month. It involves PHP's judgment and operation skills related to date and time. Friends in need can refer to the following

for details As follows:

Current month

<?php
$thismonth = date(&#39;m&#39;);
$thisyear = date(&#39;Y&#39;);
$startDay = $thisyear . &#39;-&#39; . $thismonth . &#39;-1&#39;;
$endDay = $thisyear . &#39;-&#39; . $thismonth . &#39;-&#39; . date(&#39;t&#39;, strtotime($startDay));
$b_time  = strtotime($startDay);//当前月的月初时间戳
$e_time  = strtotime($endDay);//当前月的月末时间戳

Previous month

<?php
$thismonth = date(&#39;m&#39;);
$thisyear = date(&#39;Y&#39;);
if ($thismonth == 1) {
 $lastmonth = 12;
 $lastyear = $thisyear - 1;
} else {
 $lastmonth = $thismonth - 1;
 $lastyear = $thisyear;
}
$lastStartDay = $lastyear . &#39;-&#39; . $lastmonth . &#39;-1&#39;;
$lastEndDay = $lastyear . &#39;-&#39; . $lastmonth . &#39;-&#39; . date(&#39;t&#39;, strtotime($lastStartDay));
$b_time = strtotime($lastStartDay);//上个月的月初时间戳
$e_time = strtotime($lastEndDay);//上个月的月末时间戳

The key here is t in the date function, which is used to obtain the number of days in the current month, 28 days, 29 days, 30 days, and 31 days. The number of days it contains is the number at the end of the month.
