How to get file name, file size and sub directory from given directory

In this PHP tutorial, I will tell you how to read files and sub-directory from given directory with example.

Get file path and size

In this example, I have a folder/directory “demo” within C:xampphtdocs directory.

Now using below code, You can easily get all files and their size using PHP function.

<?php
functiongetDirContents($dir,&$results=array()){
$files=scandir($dir);
foreach($filesas$key=>$value){
$path=realpath($dir.DIRECTORY_SEPARATOR.$value);
if(!is_dir($path)){
$results[]=['path'=>$path,'size'=>filesize($path)];
}elseif($value!="."&&$value!=".."){
getDirContents($path,$results);
$results[]=['path'=>$path,'size'=>filesize($path)];
}
}
return$results;
}
$fileslist=getDirContents('C:xampphtdocsdemo');
echo"<pre>";
print_r($fileslist);

<?php
function getDirContents($dir, &$results = array()){
    $files = scandir($dir);
    foreach($files as $key => $value){
        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            $results[] = ['path'=>$path,'size'=>filesize($path)];
        } else if($value != "." && $value != "..") {
            getDirContents($path, $results);
            $results[] = ['path'=>$path,'size'=>filesize($path)];
        }
    }

    return $results;
}

$fileslist = getDirContents('C:xampphtdocsdemo');
echo "<pre>";
print_r($fileslist); 

Output :

Array
(
    [0] => Array
        (
            [path] => C:xampphtdocsdemofile1.jpg
            [size] => 23708
        )

    [1] => Array
        (
            [path] => C:xampphtdocsdemofile2.jpg
            [size] => 410510
        )
)

filesize function returns the size in bytes of specified file.

Return all sub directory without files

In this example, I will use PHP glob() method that returns an array of filenames or directories.

This is smarter way to find all files having specified pattern :

<?php
print_r(glob("*.jpg"));
?>

<?php
 print_r(glob("*.jpg"));
?>

This will return all files having “.jpg” extension.

Array
(
	[0] => file1.jpg
	[1] => file2.jpg
)

Using glob method you can get all the directories and files.

$dirs = array_filter(glob('*'), 'is_dir');
print_r( $dirs);

This will return the directories without files.

$fileDir = array_filter(glob('*'));
print_r($fileDir);

This will return the directories with files.

Scan directory and files inside the specified path

$files=scandir('C:xampphtdocsdemo');
print_r($files);

This will return the array of files and directory from given path.
