php - How to retrieve all text files from multiple different directories? -

you may have heard of glob method manages retrieve files directory file containing method located on - 1 directory.

this example of code using:

<?php  foreach (glob("*.txt") $filename)  {     $time = filemtime($filename);     $files[$time] = $filename; }  krsort($files);  foreach ($files $file) { echo $file;  }  ?> 

what happens here of text files in current directory retrieved, sorted order of date modified , echoed out onto page.

the problem don't want retrieve text files one directory.

how change can retrieve files multiple directories of choice 1 page - can echo out of text files multiple directories onto 1 page rather echoing out text files one directory?

i believe need store directories want glob array not sure how retrieve it.

here example stolen page in comment above

<?php  $directory = new recursivedirectoryiterator('path/to/project/'); $iterator = new recursiveiteratoriterator($directory); $regex = new regexiterator($iterator, '/^.+\.txt$/i', recursiveregexiterator::get_match);  ?>
