How can PHP developers effectively handle escape characters in SQL queries?

To effectively handle escape characters in SQL queries, PHP developers can use prepared statements with parameterized queries. This method separates the SQL query logic from the data input, preventing SQL injection attacks and automatically escaping special characters. 

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

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");

// Bind the parameter value and execute the query
$stmt->execute(['username' => $username]);

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