What is the desired output if the file name contains additional dots? — Otto, Sep 20 '13 at 07:39
See also [`pathinfo()`](http://php.net/pathinfo), [`list`](http://php.net/list), [`preg_split()`](http://php.net/preg_split), and other such pages in the quite informative PHP manual. — outis, Sep 20 '13 at 07:50

Try with:

$info = pathinfo('Hello_world.wav');

var_dump($info);

Which gives you:

array (size=4)
  'dirname' => string '.' (length=1)
  'basename' => string 'Hello_world.wav' (length=15)
  'extension' => string 'wav' (length=3)
  'filename' => string 'Hello_world' (length=11)

So:

$a = $info['filename'];
$b = '.' . $info['extension'];

Why downvote? It seems it's the best solution (I've commented that before) – Alma Do Sep 20 '13 at 07:39
+1 for using correct function – Rajat Modi Sep 20 '13 at 07:41
@jerdiggity It works with string - not existing file. I've tested it without fil in my filesystem. – hsz Sep 20 '13 at 07:44
LOL yeah... I realized I said that in the wrong context so I deleted my comment. But yes you're right. – jerdiggity Sep 20 '13 at 07:45

Split is DEPRECATED as of PHP 5.3.0. You shouldn't use it (PHP manual). Instead, use explode:

$new_str_arr = explode('.', $ab);
$a = $new_str_arr[0];
$b = '.' . $new_str_arr[1];

You can also use preg_split():

$ab="Hello_world.wav";
$matches = preg_split('/\./', $ab);
$a = isset($matches[0]) ? $matches[0] : '';
$b = isset($matches[1]) ? '.' . $matches[1] : '';
// Print if you want by uncommenting the next line
// print $a . ' ' . $b;
