I have issue with getting particular date function with php - php

Question

I want dates like if today is Tuesday then I want a date from starting of this week to the current day and get last week date from starting of last week to the current day like if today is 11-02-2020 and Tuesday then I want date like 10-02-2020 11-02-2020 and last week dates like 03-02-2020 04-02-2020
for that, I have used below functions
function last_week_date(){
date_default_timezone_set("Asia/Kolkata");
$day = date("l");
$previous_week = strtotime("-1 week +1 day");
$start_week = strtotime("last monday",$previous_week);
$end_week = strtotime("next $day",$start_week);
$start_week = date("Y-m-d",$start_week);
$end_week = date("Y-m-d",$end_week);
return $start_week.' '.$end_week ;
}
function this_week_date(){
date_default_timezone_set("Asia/Kolkata");
$day = date("l");
$previous_week = strtotime("+1 day");
$start_week = strtotime("last monday",$previous_week);
$end_week = strtotime("next $day",$start_week);
$start_week = date("Y-m-d",$start_week);
$end_week = date("Y-m-d",$end_week);
return $start_week.' '.$end_week ;
}
but with this, I have received dates of the full week not till a particular day
can anybody help me with this

Answer 1

This function will give you the results you want. You can simply pass it a parameter which is the number of weeks forward or backward to shift the dates to get this weeks/last weeks/next weeks days:
function week_date($weeks = 0) {
$start = new DateTime("monday this week");
$end = new DateTime();
$start->modify("$weeks weeks");
$end->modify("$weeks weeks");
return $start->format('Y-m-d') . ' ' . $end->format('Y-m-d');
}
To call, use
echo week_date() . "\n"; // this week
echo week_date(-1) . "\n"; // last week
echo week_date(1) . "\n"; // next week
Output (as of Monday 2020-02-10):
2020-02-10 2020-02-10
2020-02-03 2020-02-03
2020-02-17 2020-02-17
