Are there any best practices for securely accessing and updating database values using cronjobs in PHP?

When accessing and updating database values using cronjobs in PHP, it is important to ensure that the process is secure to prevent any unauthorized access or data manipulation. One best practice is to use prepared statements to prevent SQL injection attacks. Additionally, it is recommended to restrict database user permissions to only allow necessary operations and to encrypt sensitive data before storing it in the database. 

<?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);
}

// Prepare and execute SQL statement
$stmt = $conn->prepare("UPDATE table_name SET column_name = ? WHERE id = ?");
$stmt->bind_param("si", $value, $id);

// Set variables for update
$value = "new_value";
$id = 1;

// Execute the update
$stmt->execute();

// Close the statement and connection
$stmt->close();
$conn->close();
?>
