help on picture manipulation

[alarik149]

Good evening people:).I`m a little stuck while using some pictures.here is what I need.
I have a directory "pictures/a" that contrains some pictures.I want these pictures placed in an array called $pictures,so I can use them something like $picture[1] or picture[8];.Thanks for your time.

i love this function... goes to the database, and adds every file into an array :-)
[code]
<?
function get_allfiles($dir="functions/"){
if(is_dir($dir)){
  if($handle = opendir($dir)){
  $files = array();
  while(false !== ($file = readdir($handle))){
    if(($file != ".")&&($file != "..")&&($file != "index.php")){
    $files[] = $file;
    }
  }
  closedir($handle);
  }
}else{
  return false;
}
asort($files);
return $files;
}
?>
[/code]

:) yes the function is really nice but I try to echo $files[1]; and I get nothing out:(.

if you have it pointed to the same doccument as where your searching... your $dir needs to be "."

Take a look at the [url=http://www.php.net/glob]glob()[/url] function. I find it much easier to use.

[code]function get_allfiles($dir="/pictures/a/")[/code]
the files are in "pictures/a" and the script is in root.Still dosen`t work.I`ll take a peek at glob too.

ok,I managed to get the files in an array with glob.Thanks for your help taith and kenrbnsn too.

one must remember that if a function returns a value, that has to be set into a fully different variable...
[code]
$pictures = get_allfiles("pictures/a/");
print_r($pictures);
[/code]
