Counting files...

[phpretard]

I can't figure why this displays nothing but error.

 

I am trying to count the number of files in a specified folder.

 

$dirname = "ALBUMS/".$loc;

function num_files($dirname) 
{ 
    return count(glob($dirname)); 
} 
echo num_files();

 

Here is the error: Warning: Missing argument 1 for num_files(),

$dirname needs to be passed as an argument to the function, as it is not in the same scope as the function:

 

<?php
$dirname = "ALBUMS/".$loc;
function num_files($dirname) 
{ 
    return count(glob($dirname)); 
} 
echo num_files($dirname);
?>
