Serialization
Enumerations are serialized differently from objects. Specifically, they have a new serialization code,
"E", that specifies the name of the enum case. The deserialization routine is then
able to use that to set a variable to the existing singleton value. That ensures that:
<?php
Suit::Hearts === unserialize(serialize(Suit::Hearts));
print serialize(Suit::Hearts);
// E:11:"Suit:Hearts";
?>
On deserialization, if an enum and case cannot be found to match a serialized
value a warning will be issued and false returned.
If a Pure Enum is serialized to JSON, an error will be thrown. If a Backed Enum
is serialized to JSON, it will be represented by its scalar value only, in the
appropriate type. The behavior of both may be overridden by implementing
JsonSerializable.
For print_r(), the output of an enum case is slightly different
from objects to minimize confusion.
<?php
enum Foo {
case Bar;
}
enum Baz: int {
case Beep = 5;
}
print_r(Foo::Bar);
print_r(Baz::Beep);
/* Produces
Foo Enum (
[name] => Bar
)
Baz Enum:int {
[name] => Beep
[value] => 5
}
*/
?>

With the try-catch block, it gave me this error
db.r103.websupport.seSuccessfully connected!Felmeddelande: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?,?,?) SLEEP(1)' at line 1

And this is easy
First, add
$userName=$_POST['userName'] ?? '';
$emailVerify=$_POST['emailVerify'] ?? '';
$passWord=$_POST['passWord'] ?? '';
