Use this code SHOW TABLES query returns the all tables in your selected db.

$tablesRes = mysql_query('SHOW TABLES',$conn);
while($row = mysql_fetch_row($tablesRes)){
    $tables[] = $row[0];
}

header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename=export.csv');

foreach($tables as $table){
    $query = 'SELECT * FROM '.$table;
    $result = mysql_query($query, $conn) or die(mysql_error($conn));
    //your csv code here
}
