What is the purpose of the PHP script in the forum post?

The purpose of the PHP script in the forum post is to sanitize user input before storing it in a database to prevent SQL injection attacks. This is important for security reasons as it helps protect the database from malicious input that could potentially harm the system. 

// Sanitize user input before storing in the database
$unsafe_input = $_POST['user_input'];
$safe_input = mysqli_real_escape_string($connection, $unsafe_input);

// Store the sanitized input in the database
$query = "INSERT INTO table_name (column_name) VALUES ('$safe_input')";
mysqli_query($connection, $query);
