Question

I need to do a dirname() on a file path multiple times to exclude sub-folders, so like this:

dirname(dirname(dirname(__FILE__)));

The amount of times I need to do this on a file path is completely dynamic (not fixed) so I need to somehow do it variable $x amount of times…

I could do this:

$x=6;//amount of sub-folders involved in the path

if($x==1){dirname(__FILE__);}

elseif($x==2){dirname(dirname(__FILE__));}

elseif($x==3){dirname(dirname(dirname(__FILE__)));}

elseif($x==4){dirname(dirname(dirname(dirname(__FILE__))));}//and so on.....

But thats not exactly a professional way of going about it, and it will never be reliable (if $x=9999999….).

Does anyone know how I’d go about doing this??

Answer 1

You need to invoke the dirname function $x times, that’s called a loop:

$x=6; //amount of sub-folders involved in the path
$dir = dirname(__FILE__);
while(max(0, --$x)) {
    $dir = dirname($dir);
}
