check table?

i would like to make a function like that:

Code:

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;

    }

}
