Not the prettiest code, and it certainly could be improved, but it works. try it.

$rootdirectory = "/";
$imagelist = array();
$ignoredirarray = array('secret','hidden','stats','hideme');
$ignorefilearray = array('secretimg.gif');
$URLpath=Array();
browse_images($rootdirectory,$URLpath);
print ("There are ".count($imagelist)." images.");
for ($i=0;$i<count($imagelist);$i++){
print("<BR>".$imagelist[$i]);
}
function browse_images($dir_name, $URLpath){ 
global $imagelist;
global $ignoredirarray;
global $ignorefilearray;
print("<table border='0' cellpadding=0 cellspacing=0 width='100%'>\n");
$dir = opendir($dir_name);
while($file = readdir($dir)){
if($file!= "." && $file!= ".."){
if(is_dir($dir_name . $file)){
$found_dirs[] = $file;
}else{
$found_files[] = $file;
}
}
}
closedir($dir);
if($found_dirs){
sort($found_dirs);
for($i = 0; $i < count($found_dirs); $i++){
if($found_dirs[$i]!= "." && $found_dirs[$i]!= ".."){
if(! in_array( strtolower($found_dirs[$i]),$ignoredirarray)){
Array_push($URLpath,$found_dirs[$i]);
browse_images($dir_name . $found_dirs[$i] . "/",$URLpath);
Array_pop($URLpath);
}
}
}
}
if($found_files){
sort($found_files);
for($i = 0; $i < count($found_files); $i++){
if(! in_array( $found_files[$i],$ignorefilearray)){
$extension = preg_match('/\.(.*)$/',$found_files[$i],$out);
$extension = $out[1];
$fullpath = implode("/",$URLpath)."/".$found_files[$i];
if ($extension=='gif' ¦¦ $extension=='jpg' ¦¦ $extension=='png' ¦¦ $extension=='jpeg'){
Array_push($imagelist,$fullpath);
}
}
}
}
}

<?
$images = glob("dir/{*.jpg,*.gif,*.png}",GLOB_BRACE);

?>

now you have an index of ever .jpg, .gif, and .png in dir/

access them like this $images[0] or $images[1]

[WhosAWhata]

if you want to display them on a page

<?
$numcols = "4"; //number of pics in a column
$images = glob("dir/{*.jpg,*.gif,*.png}",GLOB_BRACE);
$count = count($images);
if(!$count) die;
$html = "<table cols=\"".$numcols."\">";
foreach($images as $key => $name){
$r = $key % $numcols;
if (!$r) $html .= "<tr>";
$html .= "<td><img width=300 src=\"".$name."\"></td>";
if($r == $numcols-1) $html .= "</tr>";
}
echo $html."</table>";
?>

haven't tested, but should work

more than one way to skin a cat

<? 
$mydir = "/path/to/dir/"; 
$d = dir($mydir); 
while($entry = $d->read()) { 
 if ($entry!= "." && $entry!= "..") { 
 // this will echo the name of each file 
 // it can be changed to do whatever you like 
 echo "<p>$entry\n"; 
 } 
} 
$d->close(); 
?>

but that returns every file
glob() just returns specified extentions
i suppose it depends on your needs
i think glob is just a lot easier
...and more fun to say

[jatar_k]

yeah sry, I could have gone farther on that, kinda forgot, got sidetracked

glob is the most fun to say and the easiest though

[httpwebwitch]

wow! glob() does in one line what my script hacks up with 100. Thanks for exposing me to this function which I had never heard of before!

(I wonder what other valuable nuggets are out there, but never mentioned in my printed manuals, Wrox, O'Reilly, etc.? That's a subject for another thread)

[WhosAWhata]

i actually posted a thread to find all of the .whatever files in a directory about a year ago and that is when i was first exposed to glob()...

[zinc]

thanks for all the help guys , the scipt above looks cool but i really dont know how i should be using it. andyone with msn messenger would be great

[edit reason] no specifics thanks [/edit]

i need it to list the url and name and type of file.

i want to be able to list the files at this url

basically all i want to do is make a search box that will find files in that directory matching whatever is put into the search. there are not html files at all in the dir above, its only image files and sub directories

thanks again

send me a private message with your MSN name and exactly what you need

I think i might be able to lend a hand
(you can't post everything in the actual forum, but anything goes in the StickyMail)

glob is cool, but it's slower. Here's a link with some more information regarding the glob function...

thanks for the replys guys, but as i said when i look at a bit of script, its just text to me, i have no idea in what way i should be using this, should i be making a new php page and copying the text into it, and what are the bit i need to change to get it to work on my dir.
