how to check if folder contains only files with php

Question

I want to check if a folder contains at least 1 real file. I tried this code:

$dir = "/dir/you/want/to/scan"; 
$handle = opendir($dir); 
$folders = 0; 
$files = 0; 

while(false !== ($filename = readdir($handle))){ 
    if(($filename != '.') && ($filename != '..')){ 
        if(is_dir($filename)){ 
            $folders++; 
        } else { 
            $files++; 
        } 
    } 
} 

echo 'Number of folders: '.$folders; 
echo '<br />'; 
echo 'Number of files: '.$files;

when in folder scan are 1 subfolder and 2 real files; the code above gives me as output:

Number of folders: 0

Number of files: 3

So it seems that a subfolder is seen as a file. But i want only real files to be checked. How can i achieve that?

does this help you: https://secure.php.net/manual/en/function.scandir.php#87527 ? And check if the array is `empty()`. — , Jun 07 '16 at 11:38

based on your first line, where you specify a path, which is different to your scripts path, you should combine $dir and the $filename in the is_dir if-clause.

Why?

Because if your script is on:

/var/web/www/script.php

and you check the $dir:

/etc/httpd

which contains the subfolder "conf", your script will check for the subfolder /var/web/www/conf

It's `$dir` in his script, but this is the correct answer. – Aurel Bílý Jun 07 '16 at 11:37

You can do this job easily using glob():

$dir = "/dir/you/want/to/scan"; 
$folders = glob($dir . '/*', GLOB_ONLYDIR); 
$files = array_filter(glob($dir . '/*'), 'is_file'); 

echo 'Number of folders: ' . count($folders);
echo '<br />'; 
echo 'Number of files: ' . count($files);

You can use scandir

scandir — List files and directories inside the specified path

<?php 
$dir = "../test"; 
$handle = scandir($dir); 
$folders = 0; 
$files = 0; 
foreach($handle as $filename)
{ 
    if(($filename != '.') && ($filename != '..'))
    { 
        if(is_dir($filename))
        { 
            $folders++; 
        } 
        else 
        { 
            $files++; 
        } 
    } 
} 

echo 'Number of folders: '.$folders; 
echo '<br />'; 
echo 'Number of files: '.$files; 
?>
