Because global is specific to the SCOPE not to the variable -
variables themselves aren't tagged as global. If you add
global $text;
in your echoo() function it will work. Alternatively, you could replace
echo $text;
with
echo $GLOBALS['text'];
in your echoo() function.
See
http://www.php.net/manual/en/language.variables.php
for more info.
