how to get particular date with php

问题

I want dates like current week dates from Monday to Wednesday and last week dates from last week Monday to last week Wednesday

I have tried this code

function last_to_last_week_date(){
    $previous_week = strtotime("-2 week +1 day");

    $start_week = strtotime("last monday",$previous_week);
    $end_week = strtotime("next sunday",$start_week);

    $start_week = date("Y-m-d",$start_week);
    $end_week = date("Y-m-d",$end_week);

    return $start_week.' '.$end_week ;
}
function last_week_date(){
    $previous_week = strtotime("-1 week +1 day");

    $start_week = strtotime("last monday",$previous_week);
    $end_week = strtotime("next sunday",$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 last week dates and last to last week dates

can anybody help me with this

回答1:

You can simply fix 2 rows in your code:

$end_week = strtotime("next wednesday",$start_week);  // <-- "next wednesday"

And for the current dates:

$previous_week = strtotime("+1 day");    

Demo

Output:

2020-01-20 2020-01-22
2020-01-27 2020-01-29

DRY

You can simplify your code. Use one method in each of two:

function optimDate($prev_w){

    $start_week = strtotime("last monday",$prev_w);
    $end_week = strtotime("next wednesday",$start_week);

    $start_week = date("Y-m-d",$start_week);
    $end_week = date("Y-m-d",$end_week);

    return $start_week.' '.$end_week ;
}

And these two method become like

function last_week_date(){ 
    return optimDate(strtotime("-1 week +1 day"));
}
function curr_week_date(){ 
    return optimDate(strtotime("+1 days"));
}

Demo

In fact, this also could be optimized.
