How do I programmatically getting the startDay of the current week using PHP?

Question

Today is April 7th, and the closest the beginning date of the week is April 5.

How do I programmatically getting the startDay of the current week using PHP ?

I've tried

$dateStartWeek = date('N', strptime('%m-%d-%g', $dateString));
dd($dateStartWeek);

and tried

    function getFirstDayOfWeek(DateTime $date, $firstDay = 0) {
        $offset = 7 - $firstDay;
        $ret = clone $date;
        $ret->modify(-(($date->format('w') + $offset) % 7) . 'days');
        return $ret;
    }


    $dateStartWeek = getFirstDayOfWeek(date("y-m-d"));

By "startDay", I assume you mean the nearest Sunday previous to the current date? — esqew, Apr 07 '20 at 15:30
@0stone0, Your return `"2020-04-12"` which is the upcoming sunday. :) — code-8, Apr 07 '20 at 15:33
@cyber8200 Yea, you could use `date("Y-m-d", strtotime('sunday last week'));` — 0stone0, Apr 07 '20 at 15:34
It works, your answer is the most elegant answer. `$dateStartWeek = date("d", strtotime('sunday last week'));` — code-8, Apr 07 '20 at 15:35
Clean, one line. I don't know why others write functions to do it when we should just call it. — code-8, Apr 07 '20 at 15:36
@cyber8200 Yea, there are plenty 'hacky' solutions to this, `strtotime` with relative dates can be really useful ;) — 0stone0, Apr 07 '20 at 15:40
The answers in to the link is NOT Helping me, it confused and very tedious. The answer on this post helped me. — code-8, Apr 07 '20 at 15:44

Use the relative date format sunday last week

echo date("j F", strtotime('sunday last week'));

Use relative datetime formats - https://www.php.net/manual/en/datetime.formats.relative.php

In your case:

new \DateTImeImmutable('this week')

I got this `DateTimeImmutable @1586187250 {#437 date: 2020-04-06 11:34:10.237062 America/New_York (-04:00) }`, The answer is `5`, since Apirl 5 is the start date. – code-8 Apr 07 '20 at 15:34
Ok, in case you start your weeks on Sunday, do `new \DateTImeImmutable('this week - 1 day')` – Patrick Kusebauch Apr 07 '20 at 15:37
