I'm getting really muddled up now and my brain hurts! :( lol
Root:
Includes:
index includes dog: include("includes/dog.php");
dog includes cat: include("cat.php");
When I run index, for cat it says:
However, if I run dog, I get no problems...
I'm guessing its the path, but i've tried ./includes/cat.php to no joy...
This is because when you include a relative path, it's relative to the entry point (the first PHP file, called by the webserver).
In dog, do
include(dirname(__FILE__) . '/cat.php'); // __FILE__ is always the name of the php file it's in
It depends on where the script you are executing lies. When you execute /index.php the path of the script set to /, so all includes start from there. This means that you can find /includes/dog.php, but it's not possible to find /cats.php. Mind that, even if you are including cats.php from your /includes/dog.php script, this doesn't change the original execuption path.
When, on the other hand, you are executing /includes/dog.php, your path is set to /includes/, which is why PHP can also find cats.php.
Read Bart's comment on how to solve this.
Another way to solve this is to set the include path of files, take a look at this.
Thanks for this nice thread.
I used bart's answer to solve this issue. But I still have one question here.
I was surprised that it worked in my mate's system even without using dirname(__FILE__) so I did little research and compared both php.ini files. I noticed there is little difference at include_path parameter in php.ini.
In my php.ini it is set to Pear directory. So I commented out just to test and to my wonder it worked. This is when I realized we need to include some folder which I dont know or comment it out so that it takes default value.
