File Browser in PHP

Post Views: 2,816

Hello Friends, It’s being long time I’ve not shared anything with you but today I am going to share a php code which is nothing but a file browser code in which you can create folder, upload files, delete files and folders also you can move files and folder to another folder. It is complete basic featured file browser tool. So, Here is the code

<?php

// This function scans the files folder recursively, and builds a large array
function scan($dir) {
    $files = array();
    // Is there actually such a folder/file?
    if (file_exists($dir)) {
        foreach (scandir($dir) as $f) {
            if (!$f || $f[0] == '.') {
                continue; // Ignore hidden files
            }

            if (is_dir($dir . '/' . $f)) {
                // The path is a folder
                $files[] = array(
                    "name" => $f,
                    "type" => "folder",
                    "path" => $dir . '/' . $f,
                    "items" => scan($dir . '/' . $f) // Recursively get the contents of the folder
                );
            } else {
                // It is a file
                $files[] = array(
                    "name" => $f,
                    "type" => "file",
                    "path" => $dir . '/' . $f,
                    "size" => filesize($dir . '/' . $f) // Gets the size of this file
                );
            }
        }
    }
    return $files;
}

function upload($file, $filesize, $directory, $overwrite) {

    $filename = trim($_FILES[$file]["name"]);

    $response['filename'] = "";
    $response['error'] = true; //assuming there is an error
    $response['error_msg'] = "";

    if (empty($filename)) {
        $response['error_msg'] = "File not selected";
        return $response;
    }

    if ($_FILES[$file]["error"] > 0) {
        $response['error_msg'] = 'There is some problem please try again later.' . $_FILES[$file]["error"];
        return $response;
    }
    //file size limit checking
    if (($filesize * 1024) < $_FILES[$file]["size"]) {
        $response['error_msg'] = 'File size should less than ' . $filesize . ' kb.';
        return $response;
    }    
    //if everything alright
    if ($directory != null && $directory <> '') {
        $directory = $directory . "/";
    } else {
        $directory = "";
    }
    //if overwrite parameter is not Y then new file name needs to be generated
