It's because echo & print dont *return* string value, so you can't use them with the
concatenation operator ( . )
It's like when you do a
$bar = array();
echo 'FOO > ' . print_r($bar);
The print_r($bar) will be printed and THEN the 'FOO >' whill be echoed
That's because print_r as echo or print dosnt return value.
The fact that the ouput starts from the right to the left is most likely linked to the way php
handles concatenation, i guess.
