Php code Customize

[areeshanoor2020]

Hello Every One,
I have a problem with my website category and author.
these are Nofollow. I want to add categories and Author dofollow. Please customize below code. Thanks in Advance.

/* Nofollow to category links
/*-----------------------------------------------------------------------------------*/
add_filter( 'the_category', 'add_nofollow_cat' );
function add_nofollow_cat( $text ) {
$text = str_replace('rel="category tag"', 'rel="nofollow"', $text); return $text;
}

/*-----------------------------------------------------------------------------------*/
/* nofollow post author link
/*-----------------------------------------------------------------------------------*/
add_filter('the_author_posts_link', 'mts_nofollow_the_author_posts_link');
function mts_nofollow_the_author_posts_link ($link) {
return str_replace('<a href=', '<a rel="nofollow" href=',$link);
}

add_filter( 'the_category', 'add_nofollow_cat' );
function add_nofollow_cat( $text ) {
$text = str_replace('rel="category tag"', 'rel="dofollow"', $text); return $text;
}

/*-----------------------------------------------------------------------------------*/
/* nofollow post author link
/*-----------------------------------------------------------------------------------*/
add_filter('the_author_posts_link', 'mts_nofollow_the_author_posts_link');
function mts_nofollow_the_author_posts_link ($link) {
return str_replace('<a href=', '<a rel="dofollow" href=',$link);
}

Like this? or I think you can just return $link in the lsat one and return $text in the first one.
