This is not a bug, and here’s the reason why it appears

print_r(mixed $value, bool $return = false): string|bool

https://www.php.net/manual/en/function.print-r

as you can see, print_r has a second parameter, which is a boolean.

print_r already prints the value of the array, so there’s no need to actually echo its return value.

Return value is set to true and, when converted to a string, ends up as 1.
