//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); 

//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";

while($row = mysql_fetch_row($result)) 

$return.= 'INSERT INTO '.$table.' VALUES('; for($j=0; $j&lt;$num_fields; $j++) { $row[$j] = addslashes($row[$j]); 
$row[$j] = ereg_replace("\n","\\n",$row[$j]);
