What are some common errors or issues that PHP developers may encounter when interacting with databases in MySQL Query Browser?

One common issue that PHP developers may encounter when interacting with databases in MySQL Query Browser is not properly escaping user input, which can lead to SQL injection attacks. To solve this, developers should use prepared statements or parameterized queries to sanitize user input before executing SQL queries.

// Using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->execute();
$result = $stmt->fetch();
