i tried this ...

$a = glob("folder/*");

foreach ($a as $key) {

    echo $key."<br>";

}

but the output will be like this

folder/12345

You want scandir: https://www.php.net/manual/en/function.scandir.php

scandir ( string $directory [, int $sorting_order = SCANDIR_SORT_ASCENDING [, resource $context ]] ) : array

Returns an array of filenames on success, or FALSE on failure.

Example:

$dirArr = ['folder/12345', 'folder/46745', 'folder/57756'];

foreach($dirArr as $dir){
    $fileArr = scandir($dir);
    echo $dir.'
';
    print_r($fileArr);
    echo '
';
}

Result:

folder/12345
file1.php
file2.php

folder/46745
file1.php

folder/57756
file1.php
file2.php
file3.php
