Traversable¶

Traversable is a specific PHP interface that represents an object that can be iterated over.

Traversable is an abstract interface: it cannot be implemented directly, and instead, it must be implemented by either IteratorAggregate or Iterator.

The traversable interface is used for typing purposes.

<?php

try {
    doSomething();
} catch (\Traversable $e) {
    print "Some error was raised during processing: ". $e::class;
}

?>
