Understanding $_PATH
Array
(
[0] => 2
[1] => docs
[2] => paths
)
$_PATH is something I did some time ago as my answer to getting and parsing urls for use with mod-rewrite. It's pretty self explanatory once you know the finer points of how it works. Some of those points are:
- $_PATH[0] always displays the number of segments in a url. If the url is /one/very/segmeneted/url, $_PATH[0] will be 4. $_PATH[0] is always set.
- $_PATH[1] is the first segment of the URL, on this page it is "docs". If $_PATH[0] is set as 0, $_PATH[1] is not set.
Still foncused?
