[SOLVED] How can i return the number of files in a folder?

[cooldude832]

The title says it all i guess

[teng84]

function dirTree($dir) {

    $d = dir($dir);

    while (false !== ($entry = $d->read())) {

        if($entry != '.' && $entry != '..' && is_dir($dir.$entry))

            $arDir[$entry] = dirTree($dir.$entry.'/');

    }

    $d->close();

    return $arDir;

}

 

function printTree($array, $level=0) {

    foreach($array as $key => $value) {

        echo "<div class='dir' style='width: ".($level*20)."px;'> </div>".$key."<br/>\n";

        if(is_array($value))

            printTree($value, $level+1);

    }

}

 

Usage is as simple as this:

$dir = "<any directory you like>";

$arDirTree = dirTree($dir);

printTree($arDirTree);

Slightly shorter ... put this in the target folder

 

<?php
$num = glob("*.*");
echo count($num). " files";
?>
