如何在php中的表中插入多行

Question

我希望使用此代码通过单个查询插入多达50行，如何通过使用数组或使用循环

先谢谢

<?php


require 'conn/Session.php';

require 'conn/MySQL.php';

require_once("includes/generalFunction.php");

require_once("classes/class.SiteManager.php");

$dbcon =  new MySQL();

$siteObj =  new SiteManager();

require 'conn/checkSession.php';

if($_POST['submit']) 
{


            $content=array("student_id"=>$_POST['student_id'],"parent_id"=>$_POST['parent_id'],"student_name"=>$_POST['student_name'],"s_status"=>$_POST['s_status'],"class"=>$_POST['class'],"section"=>$_POST['section']);

            $dbcon->insert_query("tbl_attandence",$content);
            $mess="Record created successfully.";
            $url="all_attandence.php?mess=".base64_encode($mess);
            redirectPage($url);

}
?>
