Hi,
first take a look at this page:
http://www.php.net/manual/en/function.substr.php
> if (substr($text, -1) == ".")
substr($text, -1) will return the last character in string $text.
if it is a "." the if statement will evaluate to true
and it'll do the following
> {$test = substr($text, 0, -1);}
$test = substr($text, 0, -1) will return all characters of $text but the
last one and write them
to $test.
a negative third parameter means ommitting characters from the end of the
string.
The end of the string depends on the second parameter, which tells us where
to start.
if it is positive, start is the start and end is the end of the string,
if it is negative start is the end and end is the start of the string
Regards Michael
P.S. the manual is your friend, learn how to read it!!!
