List all the files and folders in a Directory with PHP recursive function

Question

I m trying to go through all of the files in a directory  and if there is a directory  go through all of its files and so on until there are no more directories to go to  Each and every processed item will be added to a results array in the function below  It is not working though I m not sure what I can do what I did wrong  but the browser runs insanely slow when this code below is processed  any help is appreciated  thanks  Code      function getDirContents  dir            results   array             files   scandir  dir                foreach  files as  key   gt   value                   if  is dir  dir  DIRECTORY SEPARATOR   value                         results      value                    else if is dir  dir  DIRECTORY SEPARATOR   value                          results      value                      getDirContents  dir  DIRECTORY SEPARATOR   value                                              print r getDirContents   xampp htdocs WORK

This solution did the job for me  The RecursiveIteratorIterator lists all directories and files recursively but unsorted  The program filters the list and sorts it   I m sure there is a way to write this shorter  feel free to improve it  It is just a code snippet  You may want to pimp it to your purposes    lt  php   path     pth to your directories and files      an unsorted array of dirs  amp  files  files dirs   iterator to array  new RecursiveIteratorIterator new RecursiveDirectoryIterator  path  RecursiveIteratorIterator  SELF FIRST      echo   lt html gt  lt body gt  lt pre gt       create a new associative multi-dimensional array with dirs as keys and their files  dirs files   array    foreach  files dirs as  dir    if is dir  dir  AND preg match            dir       d   preg replace               dir      dirs files  d    array      foreach  files dirs as  file      if is file  file  AND  d    dirname  file         f   basename  file        dirs files  d       f                  print r  dirs files       sort dirs ksort  dirs files    foreach  dirs files as  dir   gt   files     c   substr count  dir        echo  str pad      c      STR PAD LEFT    dir n       sort files  asort  files    foreach  files as  file     echo str pad      c      STR PAD LEFT      file n        echo   lt  pre gt  lt  body gt  lt  html gt       gt

A-312 s solution may cause memory problems as it may create a huge array if  xampp htdocs WORK contains a lot of files and folders    If you have PHP 7 then you can use Generators and optimize PHP s memory like this   function getDirContents  dir         files   scandir  dir       foreach  files as  key   gt   value             path   realpath  dir DIRECTORY SEPARATOR  value           if  is dir  path                 yield  path             else if  value         amp  amp   value                       yield from getDirContents  path              yield  path                     foreach getDirContents   xampp htdocs WORK   as  value        echo  value   n       yield from

My proposal without ugly  foreach  control structures is   iterator   new RecursiveIteratorIterator new RecursiveDirectoryIterator  path     allFiles   array filter iterator to array  iterator   function  file        return  file- gt isFile          You may only want to extract the filepath  which you can do so by   array keys  allFiles     Still 4 lines of code  but more straight forward than using a loop or something

To whom needs list files first than folders  with alphabetical older    Can use following function  This is not self calling function  So you will have directory list  directory view  files  list and folders list as seperated array also   I spend two days for this and do not want someone will wast his time for this also  hope helps someone   function dirlist  dir       if  file exists  dir

This will print the full path of all files in the given directory  you can also pass other callback functions to recursiveDir   function printFunc  path       echo  path   lt br gt       function recursiveDir  path   fileFunc   dirFunc        openDir   opendir  path       while    file   readdir  openDir       false             fullFilePath   realpath   path  file            if   file 0                        if  is file  fullFilePath                    if  is callable  fileFunc                         fileFunc  fullFilePath                                   else                   if  is callable  dirFunc                         dirFunc  fullFilePath                                     recursiveDir  fullFilePath   fileFunc   dirFunc                                    recursiveDir  dirToScan   printFunc    printFunc

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   gt   value           if     value          amp  amp    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   gt  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    gt  demo-image png  1    gt  filelist php  2    gt  tile png  3    gt  2015 header png  4    gt  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
