How can a user's email address be passed as a parameter in PHP functions?

To pass a user's email address as a parameter in PHP functions, you can simply define a function that accepts the email address as a parameter. Then, when calling the function, you pass the user's email address as an argument. This allows you to use the email address within the function for processing or validation. 

// Define a function that accepts an email address as a parameter
function processEmail($email) {
    // Perform actions with the email address
    echo "Email address: " . $email;
}

// Call the function and pass the user's email address as an argument
$userEmail = "user@example.com";
processEmail($userEmail);
