Default value for property of type int may not be null. Use the nullable type ?int to allow null default value¶
Description¶
When an argument is typed, and has a null default value, PHP makes it automagically nullable. That is not the case for properties, which yields this error.
Example¶
<?php
class X {
private int $i = null;
}
function foo(int $i = null) { }
?>
Solutions¶
Add the nullable type to the type definition.
Use another default value, within the current type domain.
