integer overflow tm2unixtime.c:403:4

[chongwick]

Description

The following code:

<?php
function get_date_offset($date) {
    $timezone = new \DateTimeZone('Africa/Cairo');
    $datetime = new \DateTime($date, $timezone);
    return timezone_offset_get($datetime, 'UTC');
}

$date = '0000-00-00 00:00:00';

for ($i = 0; $i < PHP_INT_MAX; $i++) {
    $date = gmdate("Y-m-d H:i:s", PHP_INT_MIN + $i);
    echo get_date_offset($date). "\n";
}

Resulted in this output:

/home/dan/php-src/ext/date/lib/tm2unixtime.c:403:4: runtime error: signed integer overflow: -9223372036854775808 - 7509 cannot be represented in type 'long long int'

But I expected this output instead:

PHP Version

8.4.2

Operating System

ubuntu 22.04

With your test I get this :

PHP Fatal error:  Uncaught TypeError: timezone_offset_get(): Argument #1 ($object) must be of type DateTimeZone, DateTime given

I was testing master which does not have this issue see here

The overflow was on 8.4.2, but I did get the same output from the master branch.

@chongwick are you sure? Did you run buildconf and configure again?

Let me clarify, I got the same output as @devnexen from the master branch. No bug there. Sorry for the confusion.
