note 8831 added to Strings

The foo-bar example gave me: "I am printing some Foo. Now, I am printing some Array[1]." This is probably due to the old php version my university department uses, and is worked around using concatenation as mentioned in the later pages on arrays: echo("\$foo->bar[1]: \"" . $foo->bar[1] . "\"\n<p>"); (the "<<<" operator won't work either, which is why I'm using echo) http://www.php.net/manual/language.types.string.php
