How can PHP variables be properly handled to ensure successful deletion of database records?

When deleting database records in PHP, it is important to properly handle variables to ensure successful deletion. One common issue is not sanitizing user input, which can lead to SQL injection attacks. To solve this, use prepared statements with parameterized queries to safely delete records from the database. 

// Assuming $id is the variable containing the record ID to be deleted
$id = $_POST['id']; // Assuming the ID is sent via a POST request

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=database_name', 'username', 'password');

// Prepare a SQL query with a parameterized statement
$stmt = $pdo->prepare("DELETE FROM table_name WHERE id = :id");

// Bind the parameter
$stmt->bindParam(':id', $id);

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