Function Name: wp_get_current_user

WordPress is a content management system that allows users to create, manage and publish their own content. One of the important features of WordPress is user authentication and authorization. When a user logs in, WordPress creates a user object which contains all the user data and capabilities that the user has.

The wp_get_current_user() function is a built-in WordPress function that retrieves the current user object. This function returns the current logged-in user’s data in the WP_User class object. It is used to retrieve the information of the currently logged-in user on the WordPress site. This function can be used to get various user details like user ID, username, email address, and other user metadata.

Example Usage:

// Get the current user object
$current_user = wp_get_current_user();

// Print the user ID
echo 'User ID: ' . $current_user->ID;

// Print the user's display name
echo 'User Display Name: ' . $current_user->display_name;

// Print the user email
echo 'User Email: ' . $current_user->user_email;

In the above example, we first get the current user object with the wp_get_current_user() function and then print the user ID, display name, and email using the object properties.
