I've tweaked @Abdelhakim Ezzahouri's code, to use Laravel's existing connection to DB instead of connecting again, entering credentials, and installing PDO, if it's not installed already.

Route::get('db_dump', function () {
    /*
    Needed in SQL File:

    SET GLOBAL sql_mode = '';
    SET SESSION sql_mode = '';
    */
    $get_all_table_query = "SHOW TABLES";
    $result = DB::select(DB::raw($get_all_table_query));

    $tables = [
        'admins',
        'migrations',
    ];

    $structure = '';
    $data = '';
    foreach ($tables as $table) {
        $show_table_query = "SHOW CREATE TABLE " . $table . "";

        $show_table_result = DB::select(DB::raw($show_table_query));

        foreach ($show_table_result as $show_table_row) {
            $show_table_row = (array)$show_table_row;
            $structure .= "\n\n" . $show_table_row["Create Table"] . ";\n\n";
        }
        $select_query = "SELECT * FROM " . $table;
        $records = DB::select(DB::raw($select_query));

        foreach ($records as $record) {
            $record = (array)$record;
            $table_column_array = array_keys($record);
            foreach ($table_column_array as $key => $name) {
                $table_column_array[$key] = '`' . $table_column_array[$key] . '`';
            }

            $table_value_array = array_values($record);
            $data .= "\nINSERT INTO $table (";

            $data .= "" . implode(", ", $table_column_array) . ") VALUES \n";

            foreach($table_value_array as $key => $record_column)
                $table_value_array[$key] = addslashes($record_column);

            $data .= "('" . implode("','", $table_value_array) . "');\n";
        }
    }
    $file_name = __DIR__ . '/../database/database_backup_on_' . date('y_m_d') . '.sql';
    $file_handle = fopen($file_name, 'w + ');

    $output = $structure . $data;
    fwrite($file_handle, $output);
    fclose($file_handle);
    echo "DB backup ready";
});

one of the best solution

  1. fisrt of all install spatie on local server https://spatie.be/docs/laravel-backup/v6/installation-and-setup

  2. now check backup working or not php artisan backup:run

  3. if backup success then u can also take it on cpanel for this go ro app/Console/Kernal.php and register this command

     protected function schedule(Schedule $schedule)
     {
         $schedule->command('backup:run')->everyMinute();
     }
    
  4. now open your cpanel and open cron job and there register this command

    /usr/local/bin/php /home/replaceyourdirectoryname/public_html/artisan backup:run > /dev/null 2>&1
    
  5. now you are successful able to take backup on live server

  6. now for on clcik download

<a href="{{ route('download') }}" class="btn btn-sm btn-primary"><i class="fa fa-download"></i>Download Backup</a>

  1. register route Route::get('/download/','DownloadController@download')->name('download');

  2. and finally controller

    <?php
     namespace App\Http\Controllers;
     use Illuminate\Support\Facades\Artisan;
     class DownloadController extends Controller{
    
    
     public function download(){
    
         Artisan::call('backup:run');
         $path = storage_path('app/laravel-backup/*');
         $latest_ctime = 0;
         $latest_filename = '';
         $files = glob($path);
         foreach($files as $file)
         {
                 if (is_file($file) && filectime($file) > $latest_ctime)
                 {
                         $latest_ctime = filectime($file);
                         $latest_filename = $file;
                 }
         }
         return response()->download($latest_filename);
     }
    

    }

Thanks for @Abdelhakim Ezzahraoui for your solution. i have just change some code. so here you can backup all table. but if you want specific then you set that table name.

function backupDatabase()
   {
       //ENTER THE RELEVANT INFO BELOW
       $mysqlHostName      = env('DB_HOST');
       $mysqlUserName      = env('DB_USERNAME');
       $mysqlPassword      = env('DB_PASSWORD');
       $DbName             = env('DB_DATABASE');
       $file_name = 'database_backup_on_' . date('y-m-d') . '.sql';


       $queryTables = \DB::select(\DB::raw('SHOW TABLES'));
        foreach ( $queryTables as $table )
        {
            foreach ( $table as $tName)
            {
                $tables[]= $tName ;
            }
        }
      // $tables  = array("users","products","categories"); //here your tables...

       $connect = new \PDO("mysql:host=$mysqlHostName;dbname=$DbName;charset=utf8", "$mysqlUserName", "$mysqlPassword",array(\PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
       $get_all_table_query = "SHOW TABLES";
       $statement = $connect->prepare($get_all_table_query);
       $statement->execute();
       $result = $statement->fetchAll();
       $output = '';
       foreach($tables as $table)
       {
           $show_table_query = "SHOW CREATE TABLE " . $table . "";
           $statement = $connect->prepare($show_table_query);
           $statement->execute();
           $show_table_result = $statement->fetchAll();

           foreach($show_table_result as $show_table_row)
           {
               $output .= "\n\n" . $show_table_row["Create Table"] . ";\n\n";
           }
           $select_query = "SELECT * FROM " . $table . "";
           $statement = $connect->prepare($select_query);
           $statement->execute();
           $total_row = $statement->rowCount();

           for($count=0; $count<$total_row; $count++)
           {
               $single_result = $statement->fetch(\PDO::FETCH_ASSOC);
               $table_column_array = array_keys($single_result);
               $table_value_array = array_values($single_result);
               $output .= "\nINSERT INTO $table (";
               $output .= "" . implode(", ", $table_column_array) . ") VALUES (";
               $output .= "'" . implode("','", $table_value_array) . "');\n";
           }
       }

       $file_handle = fopen($file_name, 'w+');
       fwrite($file_handle, $output);
       fclose($file_handle);
       header('Content-Description: File Transfer');
       header('Content-Type: application/octet-stream');
       header('Content-Disposition: attachment; filename=' . basename($file_name));
       header('Content-Transfer-Encoding: binary');
       header('Expires: 0');
       header('Cache-Control: must-revalidate');
       header('Pragma: public');
       header('Content-Length: ' . filesize($file_name));
       ob_clean();
       flush();
       readfile($file_name);
       unlink($file_name);
   }

    I have viewed all the topics available for this question , but not getting any acurate answer... anybody got clear idea to backup the current database in .sql file and download it ?

    Thanks for the great idea, I've modified your code above to use Laravel's existing DB connection, no need to re-enter credentials or use PDO extension if it's not installed (in my case it wasn't)

    Please fix the code formatting and explain why your answer is different and better than others above and also voted higher

    add wordwrap() to wrap the data like this: $data .= "('" . wordwrap(implode("','", $table_value_array),400,"\n",TRUE) . "');\n";. if the data gets too long that exceeded the limit of a line, it will be truncated and resulting error when you try to import it back into your database

    What I do like about this answer is that it actually exports all tables and not only two constant ones as in @Amins answer.
