Interface for easy identification of classes that implement PHP’s magic
__toString method.
Provided is the interface itself that establishes the contract that implementing classes have to have the magic method. As well as a dummy class that can be used in tests as a substitute for doubles, stubs, or mocks.
Open a terminal, enter your project directory and execute the following command to add this package to your dependencies:
$ composer require fleshgrinder/stringableThis command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.
IMPORTANT
You cannot throw any exceptions in a__toSringmethod due to Zend engine limitations. Please vote and comment on the this PHP request and lets hope this will be fixed.
Simply implement the interface and PHP’s magic __toString method.
class YourClass implements Stringable {
/**
* @inheritDoc
*/
public function __toString() {
return '';
}
}
