Seems to be true the second parameter is a str_replace which returns a string not an int. Casting the str_replace with (int) seems to sort it.

To resolve this error, you can cast the result of the str_replace function to an integer, as suggested. This ensures that the second argument passed to the date() function is of type int, which is what it expects.

Here’s an example of how to modify the code:

$timestamp = (int) str_replace(...);
$date = date('Y-m-d', $timestamp);

By casting the result of str_replace to an integer, you’ll ensure that the date() function gets a valid timestamp.
