Use PHP in Array and Title For Wordpress Term Creation -

so i'm trying create 2 categories when user logs in. need category names username of user logging in.

i'm new php , i've been looking through codex , know how user information can't figure out how make output in array or title.

the current code below closest i've gotten. works except php code not outputting. shows blank after creation process.

function login_createinitialcategories($user_login, $user) {      $current_user = wp_get_current_user();     wp_insert_term(         '<?php  echo $current_user->user_login; ?>',         'outings',         array(           'description' => '<?php echo $current_user->user_login ; ?> outings',           'slug'        => '<?php echo $current_user->user_login ; ?>-category'         )     );      wp_insert_term(         '<?php echo $current_user->user_login ; ?>',         'adventures',         array(           'description' => '<?php echo $current_user->user_login ; ?> adventures',           'slug'        => '<?php echo $current_user->user_login ; ?>-category'         )     );  } add_action('wp_login', 'login_createinitialcategories', 10, 2); 

do guys know way around this? code working perfectly, it's not responding/outputting php code.
