a simple sample can see the difference between include and include_once:
-----Included file (ss-1.php):
<?php
$ii = $i;
?>
-----Main file (ss.php):
<?php
for ($i = 0; $i <= 4; $i++) {
include_once "ss-1.php";
echo $ii;
}
?>
Here, you get "00000" as the result. And you will get "01234" when you change
the above "include_once" to "include". So, remember don't use
"include_once" in such a loop if you want to store some variables in a seperated file.
