%s %s cannot implement interface %s, extend Exception or Error instead¶
Description¶
Throwable is a PHP native and reserved interface. It may be used for typing, such as with catch or parameter typing, but cannot be used directly.
As the message suggest, the best is to extends an existing class that already implements Throwable, such as Error, Exception or any of their children classes.
Several interfaces are reserved by PHP: UnitEnum, BackedEnum, Throwable.
Example¶
<?php
class X implements Throwable {}
?>
Literal Examples¶
Class X cannot implement interface Throwable, extend Exception or Error instead
Solutions¶
Extends
Exceptionclass.Extends
Errorclass.Extends any of the
ExceptionorErrorclasses.
