You can try mysqldump with the dump table with the add-drop option and inside.sql file

The syntax for mysqldump : mysqldump --add-drop-table dbname tablename
also

$check = mysql_query ("SELECT * FROM `tableName` LIMIT 0,1"); /* >>limit<< is just to make it faster in case the db is huge */

if ($check){
// query was legal and could be executed by the server
}else{
// something wrong, so:
// create the table
}

try this code

<?php
function db_connect() {
$host = 'localhost';
$user = 'root';
$pass = '273568';
$line = @mysql_connect($host, $user, $pass);
return $line;
}

function mysql_is_table($db,$tbl)
{
$line = db_connect();
$tables = array();
@mysql_select_db($db);
$q = @mysql_query("SHOW TABLES", $line);

while ($r = @mysql_fetch_array($q)) { $tables[] = $r[0]; }
@mysql_free_result($q);
@mysql_close($line);
if (in_array($tbl, $tables)) { return TRUE; }
else { return FALSE; }
}

function mysql_is_database($db)
{
$line = db_connect();
$databases = array();
$q = @mysql_query("SHOW DATABASES LIKE $db", $line);

while ($r = @mysql_fetch_array($q)) { $databases[] = $r[0]; }
@mysql_free_result($q);
@mysql_close($line);
if (in_array($db, $databases)) { return TRUE; }
else { return FALSE; }
}

// example usage
$newdbName = 'testDatabase';
$newdbTable = 'testTable';

if (mysql_is_database($newdbName)) {
echo 'Yes the news database is present';

if(mysql_is_table($newdbName,$newdbTable) {
echo 'Table is present';
} else {
mysql_query("CREATE TABLE " .$newdbTable);
if(mysql_error()) {
echo mysql_error();
//do some error trapping
}
}

} else {
mysql_query("CREATE DATABASE " .$newdbName);
if(mysql_error()) {
echo mysql_error();
//do some error trapping
}
}
