What are common pitfalls when working with PHP variables in Oracle SQL databases?

One common pitfall when working with PHP variables in Oracle SQL databases is not properly sanitizing user input, which can lead to SQL injection attacks. To solve this issue, always use prepared statements with bound parameters to securely pass variables to the database. 

// Example of using prepared statements with bound parameters in PHP
$pdo = new PDO('oci:dbname=YOUR_DATABASE', 'USERNAME', 'PASSWORD');

$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();

// Fetch data from the query
while ($row = $stmt->fetch()) {
    // Process the data
}
