How can the issue of creating duplicate profiles with incomplete data be addressed in a PHP script handling user input and database interactions?

Issue: To prevent the creation of duplicate profiles with incomplete data, we can implement a check in our PHP script to verify if a profile with the same data already exists in the database before inserting a new record. 

// Check if a profile with the same data already exists in the database
$existingProfile = $pdo->prepare("SELECT * FROM profiles WHERE name = :name AND email = :email");
$existingProfile->execute(array(':name' => $name, ':email' => $email));

if($existingProfile->rowCount() > 0){
    // Profile with the same data already exists, handle accordingly
    echo "Profile with the same data already exists.";
} else {
    // Insert new profile data into the database
    $insertProfile = $pdo->prepare("INSERT INTO profiles (name, email) VALUES (:name, :email)");
    $insertProfile->execute(array(':name' => $name, ':email' => $email));
    echo "Profile created successfully.";
}
