Property x::$p cannot have type void¶
Description¶
Void is a type, that can only be used with return type, on methods or functions. Here, void represents the absence of value: this is not possible for a property or an argument. The null value is then the closest possible type that can be assigned to a property, yet representing no value.
Example¶
<?php
class x {
private void $p;
}
?>
Solutions¶
Use another type for the property.
Remove the property.
Use the null type.
