1.2.594. Invalid Cast

Some cast operations not permitted.

• (string) on an object whose class doesn’t have a __toString method

• (int) on any object, except certain PHP native ones

• (string) on an array: this will produce the Array string, which is useless.

<?php

class Foo {}

(string) new Foo();     // Error

print (string) array(); // Array

?>
