How can one ensure that special characters, such as apostrophes, are properly handled in PHP when inserting data into a database?

Special characters, such as apostrophes, can cause issues when inserting data into a database if not properly handled. To ensure that these characters are handled correctly, you can use prepared statements with parameterized queries in PHP. This method helps prevent SQL injection attacks and ensures that special characters are escaped properly before being inserted into the database. 

// 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("INSERT INTO mytable (column1, column2) VALUES (:value1, :value2)");

// Bind parameters and execute the statement
$value1 = "John O'Connor";
$value2 = "Doe";
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$stmt->execute();
