Objects as Strings

There is now a special method __toString() that can be used to allow objects to be safely used as strings.

<?php
class foo {
    public $vals = array('foo', 'bar', 'baz');

    function __toString()
    {
        return implode(' ', $this->vals);
    }
}

$a = new foo();
echo $a; // will print "foo bar baz"
?>
