Best way to get files from a dir filtered by certain extension in php [duplicate]

Solution 1:

PHP has a great function to help you capture only the files you need. Its called glob()

glob - Find pathnames matching a pattern

Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.

Here is an example usage -

$files = glob("/path/to/folder/*.txt");

This will populate the $files variable with a list of all files matching the *.txt pattern in the given path.

Reference -

• glob()

Solution 2:

If you want more than one extension searched, then preg_grep() is an alternative for filtering:

 $files = preg_grep('~\.(jpeg|jpg|png)$~', scandir($dir_f));

Though glob has a similar extra syntax. This mostly makes sense if you have further conditions, add the ~i flag for case-insensitive, or can filter combined lists.

Solution 3:

PHP's glob() function let's you specify a pattern to search for.

Solution 4:

You can try using GlobIterator

$iterator = new \GlobIterator(__DIR__ . '/*.txt', FilesystemIterator::KEY_AS_FILENAME);
$array = iterator_to_array($iterator);
var_dump($array);

Solution 5:

glob($pattern, $flags)

<?php
foreach (glob("*.txt") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
?>
