Question

i need to clean several tables in several databases before try the submits

$db_server = include('root.php');
if (!$db_server) die("Unable to connect to MySQL: " . mysql_error());
$sqla = "TRUNCATE TABLE `info`.`2012_august`";
$sqlb = "TRUNCATE TABLE `stu`.`2012_august`";
$sqlc = "TRUNCATE TABLE `stu`.`2012`";
if (@mysql_query($sqla))
    {
    echo ("success"."</br>");
    }
else
{
    echo ("un success".mysql_error()."</br>");
     }

only the first table clears its data.how can i solve this.

Answer 1

$a = array("TRUNCATE TABLE `info`.`2012_august`",   // create an array of queries
           "TRUNCATE TABLE `stu`.`2012_august`", 
           "TRUNCATE TABLE `stu`.`2012`");

foreach ($a as $value) {                            // iterate through array
    if (@mysql_query($value))
    {
        echo ("success"."</br>");
    } else {
        echo ("un success".mysql_error()."</br>");
    }
}
