In this snippet I will show you how we can get WordPress users.

Get All WordPress users with administrator role

<?php
$users = get_users( array( 'role__in' => array( 'administrator') ) );
// Array of WP_User objects.
foreach ( $users as $user ) {
    echo '<span>' . esc_html( $user->display_name ) . '</span>';
}

Get All Users

<?php
$users = get_users();
// Array of WP_User objects.
foreach ( $users as $user ) {
    echo '<span>' . esc_html( $user->display_name ) . '</span>';
}
