Removing specific items from a list

[Junitar]

Hi,

I would like to list all the items contained in a folder except for 2 or 3 specific ones.

For example, let's say I've item 1, item 2, …, item 10  in  /myFolder. I would like to list all the items of /myFolder but item 1, item 3 and item 4. I've come up with the following code which does the work but looks a bit awkward.

<?php
$dir = '/myFolder';
$filesDir = new FilesystemIterator($dir, FilesystemIterator::SKIP_DOTS);
$fileName = '';
foreach ($filesDir as $file) {
    $fileName = $file->getBasename();
    if ($fileName != 'item1' && $fileName != 'item3' && $fileName != 'item4') {
        echo $fileName.'<br>';
    }
}

Is there a simple and more elegant way to accomplish this?

 

Any help would be appreciated, thanks!

Your current solution is far more efficient than constructing an array and using in_array() on each iteration, but there's an alternative to in_array() which is much less costly: Using the keys of an associative array.

<?php
$exclude = array(
  'item1' => 1,
  'item3' => 1,
  'item4' => 1
);
$dir = '/myFolder';
$filesDir = new FilesystemIterator($dir, FilesystemIterator::SKIP_DOTS);
$fileName = '';
foreach ($filesDir as $file) {
    $fileName = $file->getBasename();
    if(!isset($exclude[$fileName])) {
        echo $fileName.'<br>';
    }
}
