[SOLVED] Return Value If Empty Directory

[r3p0]

Howdy,

I use this code to include on one page all HTML files in a directory:

 

<?php

$dir = "directory/subDirectory/";

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
      if(!is_dir($file)) include_once($dir.$file);
        }
        closedir($dh);
    }
}

?>

 

How do I extend this to insert the following code if it finds no files in the directory?

<h1>Directory is empty</h1>
<h2>Thank you please. Come again.</h2>

 

 

Thank you (please)!

scandir should work much better than that. Count how much it returns and if it's greater than 2, then it's not empty.

<?php

$dir = "directory/subDirectory/";

if (is_dir($dir)) {
    $dirContents = glob($dir . "*");

     if (count($dirContents) > 0) {
         foreach ($dirContents as $file) {
              if(!is_dir($file)) include_once($file);
         }
     }else {
             echo "<h1>Directory is empty</h1>
                     <h2>Thank you please. Come again.</h2>";
     }
}

?>

 

I prefer glob but that is how I roll.

Well since people like displaying code snippets:

$dir = 'directory/subDirectory/';
$files = scandir($dir);
if (!empty($files) && count($files) > 2) echo 'directory not empty';

 

I used !empty() because I personally find count(NULL) to be ridiculous. But you can do it. I prefer not to.

Incase that was directed towards my code...

 

glob returns an empty array. So it is not counting a "null" variable, it is counting an array that contains no items. Just an FYI on that.

[Ken2k7]

No, I was not. scandir can return a null value.

This forum is great and "you people" are amazing! Thank you for displaying code snippets. I'm curious about why "count(NULL)" is ridiculous?

[Ken2k7]

Because you're counting nothing. It's like me telling you to count the number of marbles when you have no marbles. The situation doesn't even apply.

 

By the way, don't request code snippets. People do them when they feel up to it. But this isn't a request forum. Just letting you know.
