Getting the filenames from a folder

[Krustov]

<?php
$dirname = ".";
$dh = opendir($dirnam e);
while ($file = readdir($dh))
{
if (is_dir ("$dirname/$file"))
{
print "";
}
print "$file<br>" ;
}
closedir ($dh);
?>


..
...
aaa.html
etc

The above code brings up the single and twin full stops - presumably the
option to change directorys or whatever if wanted .

Got the code snippet via google and just wondered if the above code is
the best way it could be written .

See the example in the manual, it's superior in a couple of ways.

http://uk.php.net/opendir

For example, consider the behaviour of the code you posted in the presence of
files or directories named "0".

Fair enough - just thought I would ask before I started messing around
with it .

I usually use glob() 'cause I'm lazy.

nice, i never saw that. I assume you could go *.*, can you give it
multiple matches, like *.jpg, *.gif ?

here is a func which can give an array of either folders or files:

$aListOfFiles = GetDirList($som eDirectory, 'files');
$aListOfFfolder s = GetDirList($som eDirectory, 'folders');


function GetDirList($par ent, $filesorfolders ){
$oldDir = getcwd();
$list = array();

if ($handle = opendir($parent )) {
chdir($parent);
while (false !== ($file = readdir($handle ))) {

if ($filesorfolder s == "folders"){
if ( (is_dir($file)) && ($file != ".") && ($file !=
".."))
{$list[] = $file;
}}
if ($filesorfolder s == "files"){
if ( (is_file($file) ) && ($file != ".") && ($file !=
".."))
{$list[] = $file;
}}


}// while reading
closedir($handl e);
chdir($oldDir);
}//if handle

sort($list);
reset($list);
return $list;
} //func

Yes, if you pass the GLOB_BRACE flag.

Example:

$images = glob("*.{jpeg,j pg,gif,png}", GLOB_BRACE);

You can also character class matching with glob():

$images = glob("[ab]*.gif"); // gif files starting with letter a or b

And wildcards work for sub-folder as well:

$images = glob("*/*.gif"); // gif files in all sub-folders

A real time-saver. One downside though is that the function is broken
in some versions on Win32.
