function wp_filter($wp_filter_content){
$word= array("/کلمه 1/","/کلمه 2/", "/کلمه 3/");
$replace=  array("<a href='https://somaddress.com'>".$word[0]."<a>", "#" ,str_repeat("#",strlen($word[2])));

$wp_filter_content=preg_replace($word,$replace,$wp_filter_content );

return $wp_filter_content;

}
add_filter('the_content','wp_filter');


?>

مشکل اینجاست که فقط فیلتر اول صورت میگیره
