What are common pitfalls when implementing a full-text search in PHP with MySQL?

One common pitfall when implementing a full-text search in PHP with MySQL is not properly sanitizing user input, which can leave your application vulnerable to SQL injection attacks. To solve this issue, always use prepared statements or parameterized queries to safely handle user input. 

// Example of using prepared statements for full-text search in PHP with MySQL

$searchTerm = $_POST['search_term']; // Assuming search term is coming from a form input

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

// Prepare a SQL statement with a placeholder for the search term
$stmt = $pdo->prepare("SELECT * FROM mytable WHERE MATCH(column_name) AGAINST(:search)");

// Bind the search term to the placeholder
$stmt->bindParam(':search', $searchTerm);

// Execute the prepared statement
$stmt->execute();

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

// Display or process the search results
foreach ($results as $result) {
    echo $result['column_name'] . "<br>";
}
