For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Wanted - include relative to include

Posted by enquirer (enquirer), 24 August 2005
Here is an interesting PHP problem that I have encountered I wondered if you have any effective solutions for it.

When I make my websites I like to use relative file paths, I have discovered today that when you include a page from an include page, the 2nd include is relative to the original page not the page including it.

Is there anyway to force the page to be relative to the calling page? Is there a variable that contains the path of the current php script, if there is then this could be used.

The magic "constant" $__FILE__ or __FILE__ contains the name of the current script file; if you prepend that onto your include file name, then you're making the include file relative to the current directory from whatever file you're currently in - be it the main script or somewhere lower down your included tree.

Here is the code that I?m using to generate the relative paths encase you want an actual PHP example:

$inc_path = __FILE__;
$pos = strrpos($inc_path, "/");
$inc_path = substr($inc_path, 0, $pos) . "/";

$side = $inc_path . "";
$footer = $inc_path . "";
