Note that it's a very, very bad idea to append to global
variables in a loop, unless you really, really mean to do so
in a global context. I just a while ago hung my server with
a snippet of code like this:
<?php
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim($_SERVER['PHP_SELF'], "/\\");
$GLOBALS['SITE_ROOT'] = "http://$host$uri";
while ($i < somenumber)
readfile($GLOBALS['SITE_ROOT'] = $GLOBALS['SITE_ROOT'] .
'/this/file.php');
$i++
}
?>
While it is an entertaining and unusual method of creating
very long URLs and breaking servers, it's a pretty
awesomely bad idea
(Especially considering that the script in question ran
concurrently with others of it's type, so the value in
$GLOBALS['SITE_ROOT'] was unknown.)
