Listing all files within subdirectories

[Anon]

I need to produce a list of all files within a directory arranged so that all the files are 2 levels down, i.e. there is /a/b and the files are in b. However, there might be files occasionaly in a so I really need to be able to produce a list of every single file with its path - or if not a list, be able to run some php code i've already written on the file. I need someone to show me how to get this list of all files.

Any help will be gratefully appreciated and will get a credit in the final program.

Thanks in advance,

Head over to php.net, the documentation, and check out the FileSystem functions. There you'll find functions dealing with directories and such.

It's not cleaned up, and I haven't finished really organizing this code, but it works... I put it together from several pieces of code that I had written earlier, and have been facing the same challenge. Namely, that of creating a recursive directory listing function in php. The attached code will actually generate a complete sitemap for you. I plan to release it very shortly with documentation etc.

BEGIN LONG SECTION OF CODE

<?php

$GoodDirsList = array('company', 'services', 'employee','projects');

// function RecurseDir returns an array of all the directories from DocRoot
function RecurseDir($basedir, $AllDirectories=array()) {
global $GoodDirsList;
#Create array for current directories contents
$CurrentDir=array();
#switch to the directory we wish to scan THIS IS CRITICAL... SEEMS is_dir AND is_file WON'T WORK RIGHT UNLESS YOU FIRST chdir
chdir($basedir);
$CurrentPathString=getcwd();
// find out whether we're on a windows box, or a unix box
if (stristr( $CurrentPathString, '\')) $slash='\'; # windows style
elseif (stristr( $CurrentPathString, '/')) $slash = '/'; # unix style
else die ("Could not find a slash in the directory path [_buildIndex.php line 14]");

#open current directory for reading
$handle=opendir(".");
while(false !== ( $entry = readdir($handle) )) { // otherwise directory names that evaluate to false will break the loop. Consider the directory named '0-series'
if (is_dir($entry)) {
//if (($entry!='..') & ($entry!='.')) { #Don't add special directories '..' or '.' to the list
if ($entry=='.'||$entry=='..') continue; // skip . and .. directories VERY IMPORTANT, OR YOU WILL GET AN INFINITE LOOP
if ( !in_array($entry,$GoodDirsList) ) continue; // if the needle isn't in the haystack
#build an array of contents for this directory
array_push($CurrentDir,$CurrentPathString.$slash.$entry);# unix style
//array_push($CurrentDir,$CurrentPathString.'\'.$entry); # windows style
}
}
closedir($handle);
#Loop through each directory,run RecurseDir function on each one
foreach ($CurrentDir as $key=>$value) {
array_push($AllDirectories, $value); // add the list of directories in CurrentDir to the global list of directories
$AllDirectories=RecurseDir($value, $AllDirectories);
}
chdir($basedir); #make sure we go back to our origin (not sure why original author does this)
return $AllDirectories;
}

/*
Example

$dirlist=RecurseDir($DOCUMENT_ROOT);
foreach ($dirlist as $key=>$val) {
openBox ($val);
$myFiles = getFileList($val);
closeBox();
}

This is the "Greg Grep" module.

Create 'fancy indexing' or 'grep' for certain files, and
only display those
Greg Grep will build an alternating color html table
listing the contents of a directory,
Greg Grep will let you choose the colors
Greg Grep will let you choose what file types to list
(or patterns in filenames)
Greg Grep configuration variables begin with 'cfgGG_'
to avoid namespace collisions.

####HISTORY#####
v. 0.01 first version

v. 0.1
rewrote the whole thing, adding icons, and get current directory

v. 0.2 Greg Rundlett [e-mail] 08/29/2001
added the maintainer option

v. 0.3 Greg Rundlett [e-mail] 09/10/2001
integrated with the VAN extranet
corrected filter bug
moved images to /images
added ppt.gif
added line to describe "NEW" icon

v. 0.4 Greg Rundlett [e-mail] 11/09/2001
added support for listing files chronologically v. alphabetically

v. 0.5 Greg Rundlett [e-mail] 02/26/2002
put the display into a round-corner box, then extracted the display into an
outside function
removed the internal call to getFileList, so that this file could become
part of the siteMapper, and also removed the $cfgGG_path variable, since now
you supply the name of the directory at the time you call getFileList(). use getcwd()
if you want to make it dynamic in a nav.

ver 1.1 added $expiresDays

gives the ability to control the expiry date,

ie. the amount of time before something was stale

function isNew ($date,$expiresDays) {
$epoch = time();
$stale = ($epoch-($expiresDays2460*60));
$formattedDate = date ('m/d/y',$date);
if ($date > $stale) {
return true;
}
else return false;
}

BubbleSort:

Performs a bubble sort on a give array.

Parameters:

$sort_array - the array to be sorted

$reverse - sorts the array in reverse order if set to non-zero

Output:

Returns the sorted array.
