What is the issue with using the ' character in SQL insert statements in PHP?

When using the ' character in SQL insert statements in PHP, it can cause syntax errors or SQL injection vulnerabilities if not handled properly. To solve this issue, you can use prepared statements with parameterized queries to safely insert data into the database without worrying about special characters. 

// Example of using prepared statements to safely insert data into the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

$name = "John O'Connor";
$email = "john@example.com";

$stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);
$stmt->execute();
