What steps can be taken to ensure that the database is properly filled before executing queries in PHP?

Before executing queries in PHP, it is important to ensure that the database is properly filled with the necessary data. One way to achieve this is by creating a script that populates the database with the required information before running any queries. This script can be run manually or automatically before the PHP script that contains the queries. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Populate the database with necessary data
$sql = "INSERT INTO table_name (column1, column2, column3) VALUES ('value1', 'value2', 'value3')";
if ($conn->query($sql) === TRUE) {
    echo "Database populated successfully";
} else {
    echo "Error populating database: " . $conn->error;
}

$conn->close();
?>
