How do I check the total number of files in a folder?

[MrCat]

I want to use a loop to list the file names in a folder. How do I find out the total number of files in the folder so I know when to end the loop? I can't use 'file exists' because the file names could be anything.

If you use PHP5, then you can do something like this

PHP Code:

<?php

$file = scandir("path/to/your/folder");

foreach($file as $key => $value) {

    if(is_file($value)) {
    $total++; // Counter
    echo "$value<br />\n";
    }

}

echo "<p>Total files: $total</p>";

?>

If you dont use PHP5, then do something like this

PHP Code:

<?php

$dir = "path/to/your/folder";

if ($check = opendir($dir)) {

    while(($file = readdir($check)) !== false) {
    
        if (is_file($file)) {
        $total++; // Counter
        echo "$file<br />\n";
        }
    
    }
    
}

echo "<p>Total files: $total</p>";

?>

I use something like this:

$files = array();
$dir = opendir('./smily');
while(($file = readdir($dir)) !== false)
{
 if($file !== '.' && $file !== '..' && !is_dir($file))
 {
   $files[] = $file;
 }
}
closedir($dir);
sort($files);

requesting the lenght of the array will get you the number of files.
and to go through all these files:
[code]
for($j=0; $j<(count($files)-1); $j++)
{
echo ($files[$j]);
}
?>
