[Resolved] display certain file names in dir

[aconway]

I a trying to write a php script that displays file names in a dir that relate to a certain category... kind of like this:

images/dog_1.jpg
images/dog_2.jpg
images/dog_3.jpg

There will be other categories in the dir.

So far all I have been able to is display all the files in a dir.

$directory = 'images/';
$directory = 'images/';
$directoryFiles = array();
$category = 'dog';

if ($handle = opendir($directory)) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != "..") {

    $directoryFiles[] = $file;
   }
   }
   closedir($handle);
}

for($i=0; $i<count($directoryFiles); $i++) {
          echo $directory.$directoryFiles[$i]; print "\n";
}

If it's just a naming convention place this conditional in there.

if ($file != "." && $file != "..") {
   if(strpos($file, $category) !== false) {
      $directoryFiles[] = $file;
   } 
}

I thought that I was putting the results into an array and I didn't know how to search an array.

Thanks LordShryku

Well, you could do it that way as well. Using the strpos call just fills the array with that specific category.

one concern what if I have a category dog and dogs

when getting images for dog I will get dog and dogs, I don't think that this will be a problem, but who knows

[LordShryku]

Well, based on your naming convention, you could search for "dog_" instead of just "dog".

you're on the ball.

I think that should solve my problem.
