PHP uses references in for-loop-CodePudding

I am looping through a for-loop to fill an array with dates. With each iteration I want to increase the date variable by one day.

$myDate = date_create(date_default_timezone_get());
$myArr;
for ($i = 0; $i <= 1; $i  ) {
    $myArr[$i] = $myDate;
    $myDate->modify(' 1 day');
}

What it returns to me if the current date is 06-November-2021:

echo date_format($myArr[0], 'd.m.Y'); //08.11.2021
echo date_format($myArr[1], 'd.m.Y'); //08.11.2021

I would expect that it returns 06.11.2021 and 07.11.2021 but it seems it uses some kind of references instead of values in my array. Can someone explain?

CodePudding user response：

you should create a new date and assign it to array try this

<?php
$myDate = date_create(date_default_timezone_get());
$myArr;
for ($i = 0; $i <= 4; $i  ) {
    $myArr[$i] = date_create(date_format($myDate,'d.m.Y'));
    $myDate->modify(' 1 day');
}

echo "<pre>";
print_r($myArr);
echo "</pre>";
?>

result
