check table?

i would like to make a function like that:

function checktable($table) {
  global $DB_site;

  if table exists {
    event
  } else {
    other event
  }
}

what is the best aproach? thanks.

can be achieved in different ways.. one way would be:

PHP Code:

function does_table_exist($tableName)
{
$myquery = "SELECT COUNT(*) FROM $tableName";
$myresult = mysql_query($myquery);
$mynumrows = @mysql_num_rows($myresult);
if($mynumrows)
{return TRUE;}
else
{return FALSE;}
} 

if it clashes with vbulletin structure, convert general MYSQL commands to vb MYSQL functions/objects. (Like instead of "mysql_query" use "$DB_site->query_first")

PHP Code:

function table_exists($tblName) {
    global $DB_site;

    $check = $DB_site->query_first("CHECK TABLE $tblName");
    if (!strstr($check['Msg_text'], 'exist')) {
        return true;
    } else {
        return false;
    }
}
