PHP gets the start date and end date for this week and last week

<?phpheader (' content-type:text/html; Charset=utf-8 '); $date =date (' y-m-d ');  Current date $first=1; $first =1 represents the start date of the week Monday for the beginning of 0 per Sunday for the start date $w=date (' W ', Strtotime ($date));  Get the day of the current week Sunday is 0 weeks a to Saturday is 1-6 $now _start=date (' y-m-d ', Strtotime ("$date-". $w? $w-$first: 6). ' Days '); Gets the start date of the week, if $w is 0, then represents Sunday, minus 6 $now_end=date (' y-m-d ', Strtotime ("$now _start +6 Days");  This week's End date $last_start=date (' y-m-d ', Strtotime ("$now _start-7 Days"));  Last week start date $last_end=date (' y-m-d ', Strtotime ("$now _start-1 Days"));  Last week End date echo ' This week start date: ', $now _start, ' <br/> '; Echo ' This week's End date: ', $now _end, ' <br/> '; Echo ' last week start date: ', $last _start, ' <br/> '; Echo ' last week's End date: ', $last _end, ' <br/> ';

Note: Since the foreign week begins in Sunday, the Chinese habit starts from Monday, so the direct use of Strtotime ("last Monday") will result in incorrect results.
