I want to populate the array values into database in PHP.

<?php
include_once("config.php");

$videoDetailsStr = $_POST['videoDetailsData'];

$videoDetails = explode(",",$videoDetailsStr);
              
$thumbnailImage = mysql_real_escape_string($videoDetails[0]);

$title = mysql_real_escape_string($videoDetails[1]);

$category = mysql_real_escape_string($videoDetails[2]);

$description = mysql_real_escape_string($videoDetails['3']);

$videoLink = mysql_real_escape_string($videoDetails['4']);

$result = mysql_query("INSERT into videoDetails(thumbnailImage,title,category,description,videoLink) 				values('$thumbnailImage','$title','$category','$description','$videoLink')");

if($result)
{
echo "success";
}

mysql_close();
?>

<!--Here is my jQuery-->
