What are the potential pitfalls of editing data directly in a database table in PHP?

Editing data directly in a database table in PHP can lead to SQL injection vulnerabilities if input data is not properly sanitized. To prevent this, it is recommended to use prepared statements with parameterized queries to securely interact with the database. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare('UPDATE table SET column = :value WHERE id = :id');

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

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