Are there any legal implications or regulations to consider when trying to access or store a user's mobile phone number without explicit consent?

When trying to access or store a user's mobile phone number without explicit consent, you may be violating privacy laws such as GDPR or CCPA. It is important to always obtain consent from the user before collecting their personal information, including their phone number. To ensure compliance, you should clearly explain why you need their phone number and how it will be used before requesting it. 

// Check if user has given consent before storing their phone number
if ($user->hasGivenConsent()) {
    $phoneNumber = $_POST['phone_number'];
    // Store the phone number in the database
    // Proceed with any necessary actions
} else {
    // Display a message or redirect the user to obtain consent
}
