How to get page’s ID if I know the title only?

Is there an exact opposite funciton to this one:

get_the_title(ID) 

I know there’s:

get_the_id()

But it doesn’t seem to accept any arguments.

So, basically, I’m looking for something like:

$title="Something";
get_the_id($title);

I already know this solution:

 global $wpdb;
 $post_name = get_query_var('name');
 $post_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = $post_name");

But maybe there’s something bulit-in that I’m missing?

I’m not sure how to get it via the title, but you can get it via the slug (which is often more useful in my experience) using this:

Just change “$page” to “$post” if you want to return slugs for posts instead of pages.

G’luck!
