获取文件和文件夹计数

Question

In my lyrics application, I'm using a multi-dimensional array to print the artists and album/track counts.

$test_arr = [
    /* artist               albums  tracks */
    [ "Green Day",          "8",    "26",   ],
    [ "Remy Zero",          "1",    "2",    ],
    [ "System of a Down",   "1",    "1",    ],
    [ "Modern Talking",     "1",    "1",    ],
    [ "Snow Patrol",        "1",    "2",    ],
    [ "Linkin Park",        "6",    "18",   ],
    [ "3 Doors Down",       "5",    "13",   ],
    /* ... */
];

In the array, I enter the album and track counts manually. I don't want to do that. Is there a way to add them with PHP?

Take 3 Doors Down for example. If I go to folder properties of 3 Doors Down, there I can see:

Contains:   13 Files, 5 Folders

and the folder tree of 3 Doors Down

Is there a way to count the total folders and files in a given directory?

Answer 1

To count all files and folders in a directory:

count( glob( 'directory/*' ) );

To just count directories:

$i = 0;
$ps = glob( 'directory/*' );
foreach( $ps as $p )
{
    if( is_dir( $p ) )
        $i++;
}
