--EXPECTF--
Original object:
object(DateInterval)#1 (%d) {
["from_string"]=>
bool(true)
["date_string"]=>
string(%d) "next weekday"
}
Serialised object:
string(%d) "O:12:"DateInterval":2:{s:11:"from_string";b:1;s:11:"date_string";s:%d:"next weekday";}"
Unserialised object:
object(DateInterval)#2 (2) {
["from_string"]=>
bool(true)
["date_string"]=>
string(%d) "next weekday"
}
Calling __serialize manually:
array(2) {
["from_string"]=>
bool(true)
["date_string"]=>
string(%d) "next weekday"
}
Calling __unserialize manually:
object(DateInterval)#3 (2) {
["from_string"]=>
bool(true)
["date_string"]=>
string(%d) "next weekday"
}
Used serialised interval:
object(DateTimeImmutable)#4 (3) {
["date"]=>
string(26) "2022-04-25 16:25:11.000000"
["timezone_type"]=>
int(2)
["timezone"]=>
string(3) "BST"
}
