Date values of yesterday and previous 7 days or any days in PHP

Calculate previous dates with DateTimeImmutable

For calendar-day calculations, using DateTimeImmutable and relative modification is clearer than subtracting a fixed number of seconds.

$today = new DateTimeImmutable('today');
for ($i = 1; $i <= 7; $i++) {
    echo $today->modify("-$i day")->format('Y-m-d D') . "<br>";
}

You must have seen how to get today date by using date function. By changing the date value we can get the dates of yesterday. Same way we can extend this to get date values of last 7 days. Or we can extend this to get dates between any to differences.

Let us find out the date value of yesterday.

$m= date("m"); // Month value

$de= date("d"); //today's date

$y= date("Y"); // Year value

echo date('d-m-y:D', mktime(0,0,0,$m,($de-1),$y));

Last seven days date value we can find out by using a for loop. Here is the output of the code.

Here is the code.

$m= date("m");
$de= date("d");
$y= date("Y");
for($i=0; $i<=15; $i++){
echo date('d-m-y:D',mktime(0,0,0,$m,($de-$i),$y)); 
echo "<br>";
}

Using strtotime()

We can create unixtime stamp from text string by using strtotime()

for($i=0; $i<=15; $i++){

echo date('m-d-Y: D',strtotime("$i day"))."<br>";

}

Output is here

Does this work if the date is 4th of January (for example)

smo	02-05-2010
Yes this will work perfectly. Try with March 1st of 2008 also. For testing you need to change the date of your PC or server.
