Instances of classes that do not derive from the "Throwable" interface cannot be used in a PHP "throw" statement.
|
||
|
|
|
||
|
|
Many built-in exceptions such as "Exception" and the SPL exception classes do implement the "Throwable" interface and can be extended when creating custom exceptions.
|
||
|
|
|
||
|
|
This rule raises an issue when an instance of a class that does not implement the "Throwable" interface is used in a "throw" statement .

class NoThrowable {}
|

|
|
||

// Implementation of the Throwable methods
