I have DirectoryIndex index.php
and want to include './';
But I get failed to open stream: Is a directory
Of course I can include substr($someString, -1)==='/'?$someString.'index.php':$someString;
, but is there an easier way? Maybe something in .htaccess or php.ini?
No is an answer.
You can't include a directory. PHP will only accept a valid file as an argument for include, so if you want to be able to use "./", or "somedir/" and have it find the index.php file in that dir, you could always write a function which takes the dir as an argument and returns a full path to the index file within.
Something like:
function index($dir){
return substr($dir, -1) === '/' ? $dir.'index.php' : $dir;
}
Then you could call include index("./");
or some other directory name and have it return the proper string.
