Here's a modified version of Hors answer, works slightly better for my case, as it strips out the base directory that is passed as it goes, and has a recursive switch that can be set to false which is also handy. Plus to make the output more readable, I've separated the file and subdirectory files, so the files are added first then the subdirectory files (see result for what I mean.)
I tried a few other methods and suggestions around and this is what I ended up with. I had another working method already that was very similar, but seemed to fail where there was a subdirectory with no files but that subdirectory had a subsubdirectory with files, it didn't scan the subsubdirectory for files - so some answers may need to be tested for that case.)... anyways thought I'd post my version here too in case someone is looking...
function get_filelist_as_array($dir, $recursive = true, $basedir = '', $include_dirs = false) {
if ($dir == '') {return array();} else {$results = array(); $subresults = array();}
if (!is_dir($dir)) {$dir = dirname($dir);} // so a files path can be sent
if ($basedir == '') {$basedir = realpath($dir).DIRECTORY_SEPARATOR;}
$files = scandir($dir);
foreach ($files as $key => $value){
if ( ($value != '.') && ($value != '..') ) {
$path = realpath($dir.DIRECTORY_SEPARATOR.$value);
if (is_dir($path)) {
// optionally include directories in file list
if ($include_dirs) {$subresults[] = str_replace($basedir, '', $path);}
// optionally get file list for all subdirectories
if ($recursive) {
$subdirresults = get_filelist_as_array($path, $recursive, $basedir, $include_dirs);
$results = array_merge($results, $subdirresults);
}
} else {
// strip basedir and add to subarray to separate file list
$subresults[] = str_replace($basedir, '', $path);
}
}
}
// merge the subarray to give the list of files then subdirectory files
if (count($subresults) > 0) {$results = array_merge($subresults, $results);}
return $results;
}
I suppose one thing to be careful of it not to pass a $basedir value to this function when calling it... mostly just pass the $dir (or passing a filepath will work now too) and optionally $recursive as false if and as needed. The result:
[0] => demo-image.png
[1] => filelist.php
[2] => tile.png
[3] => 2015\header.png
[4] => 2015\08\background.jpg
Enjoy! Okay, back to the program I'm actually using this in...
UPDATE Added extra argument for including directories in the file list or not (remembering other arguments will need to be passed to use this.) eg.
$results = get_filelist_as_array($dir, true, '', true);
