Can anybody provide me with a good ans secure PHP script to download SQL database?

Could you please check and fix any issues with this class?

$dbhost = '';
$dbuser = '';
$dbpass = '';
$dbname = '';

function backup_tables($host,$user,$pass,$name,$tables = '*')
{

    $link = mysql_connect($host,$user,$pass);
    mysql_select_db($name,$link);
    mysql_query("SET NAMES 'utf8'");

    //get all of the tables
    if($tables == '*')
    {
        $tables = array();
        $result = mysql_query('SHOW TABLES');
        while($row = mysql_fetch_row($result))
        {
            $tables[] = $row[0];
        }
    }
    else
    {
        $tables = is_array($tables) ? $tables : explode(',',$tables);
    }
    $return='';
    //cycle through
    foreach($tables as $table)
    {
        $result = mysql_query('SELECT * FROM '.$table);
        $num_fields = mysql_num_fields($result);

        //$return.= 'DROP TABLE '.$table.';';
        $row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
        $return.= "\n\n".$row2[1].";\n\n";

        for ($i = 0; $i < $num_fields; $i++) 
        {
            while($row = mysql_fetch_row($result))
            {
                $return.= 'INSERT INTO '.$table.' VALUES(';
                for($j=0; $j<$num_fields; $j++) 
                {
                    $row[$j] = addslashes($row[$j]);
                    $row[$j] = str_replace("\n","\\n",$row[$j]);
                    if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
                    if ($j<($num_fields-1)) { $return.= ','; }
                }
                $return.= ");\n";
            }
        }
        $return.="\n\n\n";
    }

    //save file
    $handle = fopen('db-backup-'.time().'-'.(md5(implode(',',$tables))).'.sql','w+');
    fwrite($handle,$return);
    fclose($handle);
}

backup_tables($dbhost,$dbuser,$dbpass,$dbname);

I think I should not use Drop Table?

We don't know whether you want to drop tables or not.

Anyways, why don't you use the ACP -> Tools & Maintenance -> Database Backup functionality? It should work without any problem, unless the question doesn't concern MyBB - but then it shouldn't be asked on this forum.

Thanks D666 this class is for non MYBB script! I am on Godaddy and can't make a backup of DB cause it times out!

Could you please help! I only want to make a backup this class works but it adds Drop Table to .sql file and many say that could cause errors during import!

MyBB backup doesn't add this Drop Table!
