Question

My application has a video with the name of the folder. I want to raed the entire file only in this folder, which I made almost, it does not show any folder in the video folder, except for the .DS_Store I currently applied, if the condition is to hide it, but I want the perfect solution. can someone help: - my code is: ----

$dir = "../videos/";
$dh  = opendir($dir);

print '<select size="4" name="vidfile">';

while (($file = readdir($dh)) !== false) {

    if (is_file($dir.'/'.$file) && $file != "." && $file != "..") {

        if ($file!=".DS_Store") {

            print "<option>{$file}</option>";
        }
    }          
}

print '</select>'; 

closedir($dh);

Quick and easy solution

You can make your life easier and use DirectoryIteratorto go through the directory.

echo '<select name="vids" size="4">';
foreach( new DirectoryIterator('/path/to/videos') as $file) {
    if( $file->isFile() === TRUE && $file->getBasename() !== '.DS_Store') {
        printf("<option>%s</option>\n", htmlentities($file->getBasename()));
    }
}
echo '</select>';

Enhancement: decoupling directory filtering from a SelectBox building

foreach, a FilterIterator , accept(). DirectoryIterator FilterIterator. , , :

class MyFilter extends FilterIterator
{
    public function accept()
    {
        return $this->current()->isFile() === TRUE &&
               $this->current()->getBasename() !== '.DS_Store';
    }
}

$iterator = new MyFilter(new DirectoryIterator('/path/to/videos'));

foreach , accept(). accept() FALSE, .

SelectBox :

echo '<select name="vids" size="4">';
foreach( $iterator as $file) {
    printf("<option>%s</option>\n", htmlentities($file->getBasename()));
}
echo '</select>';

FilterIterator

FilterIterator , , , SelectBox, FilterChainIterator :

$iterator = new FilterChainIterator(new DirectoryIterator('/path/to/videos'));
$iterator->addCallback(function($file) {
    return $file->isFile() === TRUE &&
           $file->getBasename() !== '.DS_Store';});

$dir = "../videos";
$mask = "*";
// $mask = "*.{wmv,mpeg,mpg}";  // get only files of these types

$files = glob($dir."/".$mask);
$excluded_files = array(".DS_store");
$html = null;    

if (count($files) > 0)
foreach ($files as $file)
