Answer 1

Within your json_decode function you've specified 'true', this will make return an array.

You're then trying to access this information as an object, which won't work. Plus the fact that you are given two arrays back would suggest that you're going to need a foreach statement to insert both pieces of data in to the database.

Have another look in to foreach statements and arrays, there's plenty of information around to give you a hand.

For example:

$array = json_decode($data,true);

foreach($array as $item) {
    mysql_query("INSERT INTO `db512172115`.`trial` (name, phone, city, email) 
  VALUES ('".$item['name']."', '".$item['phone']."', '".$item['city']."', '".$item['email']."')");

}

To add on to this, you're using a deprecated mysql_* function, you should look in to using mysqli or PDO for increased security.

This is another easy way

<?php
    $json_value = file_get_contents('your_json_data_link');
    $array = json_decode($json_value,true);
    require_once 'db.php';
    foreach($array as $item) {
        $insert_value = "INSERT INTO `db512172115`.`trial` (name, phone, city,email)VALUES 
        ('".$item['name']."', '".$item['phone']."', '".$item['city']."', '".$item['email']."')");

        if ($con->query($insert_value ) === TRUE) {
            echo "Record Successfully<br>";
        }
        else
        {
            echo "Error: " . $insert_value . "<br>" . $con->error;
        }
    }
?>
