How to add SEO-friendly meta tags dynamically in WordPress using PHP?

I am working on a WordPress website and trying to improve the SEO structure of different pages.

Currently the meta title and meta description are the same for many pages, and I want to generate them dynamically using PHP based on the page content.

My goal is to:

1. Automatically generate meta title from the post title
2. Generate meta description from the first paragraph or excerpt
3. Ensure the meta tags are properly inserted in the <head> section

Example:

<meta name="description" content="Dynamic description here">
<meta name="keywords" content="dynamic keywords">

What is the best way to implement dynamic SEO meta tags in WordPress using PHP functions?

Should this be done inside functions.php or through a custom plugin?

Any code examples or best practices would be helpful.
