What are some best practices for constructing a PHP SQL query that involves searching for partial values in a specific column?

When constructing a PHP SQL query that involves searching for partial values in a specific column, it is best practice to use the SQL LIKE operator along with placeholders to prevent SQL injection attacks. This allows you to search for partial matches within a specific column without compromising the security of your application. 

// Assuming $searchTerm contains the partial value you want to search for
$searchTerm = "example";

// Prepare the SQL query with a placeholder for the search term
$sql = "SELECT * FROM table_name WHERE column_name LIKE :searchTerm";

// Bind the search term to the placeholder using PDO prepared statements
$stmt = $pdo->prepare($sql);
$stmt->bindValue(':searchTerm', '%' . $searchTerm . '%', PDO::PARAM_STR);
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();
