Remove folders from php scandir listing

Question

I have a php script $filelist = scandir('myfolder/') which list outs files from my folder. But it is adding child folders also to the array so that they are also populated when i print the result using foreach. I want to remove folders from getting added to the array. How can I do this??

Answer 1

Simple way

$dir = 'myfolder/';
$filelist = scandir($dir);
foreach ($filelist as $key => $link) {
    if(is_dir($dir.$link)){
        unset($filelist[$key]);
    }
}

Answer 2

A clean concise solution could be to use array_filter to exclude all sub-directories like this

$files = array_filter(scandir('directory'), function($item) {
    return !is_dir('directory/' . $item);
});

This effectively also removes the . and .. which represent the current and the parent directory respectively.
