tjekke om der findes en tabel

Denne her fandt jeg inde på php.net -> http://dk.php.net/manual/en/function.mysql-list-tables.php

function mysql_table_exists($dbLink, $database, $tableName)
{
    $tables = array();
    $tablesResult = mysql_list_tables($database, $dbLink);
    while ($row = mysql_fetch_row($tablesResult)) $tables[] = $row[0];
    return(in_array($tableName, $tables));
}

men en anden har skrevet denne derinde, som nok er bedre til dig

mysql_connect("server","usr","pwd")
    or die("Couldn't connect!");
mysql_select_db("mydb");

$tbl_exists = mysql_query("DESCRIBE sometable");
if (!$tbl_exists) {
mysql_query("CREATE TABLE sometable (id int(4) not null primary key,
somevalue varchar(50) not null)");
}

takker for point
