datetime With Multiple Signs
There can be only one sign character, when instantiating a DateTime object.
Until PHP 8.2, it was possible, though confusing, to use multiple sign + and -. This is considered a bad practice.
PHP code
<?php
$time = new \DateTimeImmutable("-+-1 year");
echo $time->format('Y/m/d H:i:s'), "\n";
?>
Before
2024/10/18 10:15:30
After
2022/10/18 10:15:30
PHP version change
This behavior changed in 8.2.
