empty folder???

[postbil.com]

Hello phpfreaks ..

I'm trying to learn php .. and now I've made a small function which looks in the folder, the folder I empty it should write "The folder is empty", and if the folder is not empty, it should write "folder is not empty". But no matter how many Filder are in the folder, get the same result "folder is not empty" ..

I hope someone can help me and tell what I'm doing wrong.

Here is my function:

<?php

function insertFile ($imageFunction){

// First make sure the folder is empty

        $dh = opendir($imageFunction['dir']);

 

// Create a array for all file names in the folder

        $files = array();

        $files[] = readdir($dh);     

       

// If the count of filenames is more than 0       

        if(count($file) > 0) {

            echo 'The folder is not empty';

        }else{

            echo 'The folder is empty.';

        }

       

        echo count($file);

 

   

    closedir($dh);

   

}

?>

Have a look at this:

 

function is_empty_folder($dir) {
if (is_dir($dir)) {
   $dl=opendir($dir);
   if ($dl) {
       while($name = readdir($dl)) {
   if (!is_dir("$dir/$name")) { //<--- corrected here
       return false;
       break;
       }
   }
       closedir($dl);
       }
   return true;
   } else return true;
}

Even an empty folder has two files in it. "." and "..", filter those out.

To follow on from teamatomic post,

as your counting from readdir your need to expect the . and .. file nodes so

update

if(count($file) > 0) { 

to

if(count($file) > 2) {

Or you can strip out those files from being seen:

 

if(is_dir($dir)){
  $dir_array = scandir($dir);
  foreach($dir_array as $file) {
    if(stripos($file, '.') > 0) {
    echo "There are files in the folder";
    } else {
     echo "There are no files";
}
}
}

Thank you all ..

But I have just two more questions ..

How can it be that readdir () will always be '. " and '..' even if the folder is empty?

and how can I give you poing?

[teamatomic]

Yes, even an empty folder will have "." and ".." it a feature of the OS.

}
}
}

 

 

folder "." is go back 1 folder back, like u are at c:\windows\system32, it will go back to c:\windows

folder ".." is go back to root, i think, so, u will be at c:\ after u clicked it

 

 

most files has extensions, so, your way just strip many files out too

I have used this method many different times on many different projects and it has never stripped out any proper files out of the count

No. dot refers to the current folder. dot-dot refers to the parent folder.

And tell me, how would you ever click on one. The file system itself uses them for traversing the directory tree.
