Re: substr....what does this mean? (newbie)

From what it looks like, R, this code: if (substr($text, -1) == ".") {$test = substr($text, 0, -1);} checks to see if there is a period at the end of text. If there is, it simply assigns $test to be $text without the '.' . I'm rather new at this, so if someone has a counterclaim to what this might be, feel free to speak up. J.
