PHP: Get last directory name from path

问题

I am writing one function for getting some different database query. Now things are going well but only need to get last directory name from defined path.

$qa_path=site_root('/learnphp/docs/');

I wan to get only docs from above path. Here site_root is nothing but $_SERVER['DOCUMENT_ROOT'] So how can I get only docs ?

Thanks

回答1:

Easiest way would be to use basename($yourpath) as you can see here: http://php.net/basename

回答2:

Provided answer doesn't work if your string contains the file at the end, like :

basename('/home/mypath/test.zip');

gives

test.zip

So if your string contains the file, don't forget to dirname it first

basename(dirname('/home/mypath/test.zip'));

gives

mypath

This is the easiest way:

<?php
  echo basename(getcwd());
?>

getcwd() = give your full directory path basename() = give you last directory

回答4:

Try explode('/', '/learnphp/docs/') to split the string into array locations. Then fetch the last location.

Here is more info: http://php.net/manual/en/function.explode.php

回答5:

you can use this simple snippet:

$qa_path=site_root('/learnphp/docs/');
$qa_path = explode("/", $qa_path);
$qa_path = $qa_path[count($qa_path) - 1];

回答6:

$qa_path=explode('/', '/learnphp/docs/');
echo $qa_path[2]; // output docs

回答7:

This will help you

$qa_path=site_root('/learnphp/docs/');
$q_path = explode ("/", $qa_path);
$lastV =  end($q_path);

This gives you the current directory name: echo basename(dirname(__FILE__));
