Question

This is quite difficulty for me. Please help.
I’ve a website created with cake PHP in root domain (say mysite.com) and a blog in a directory called “blog” (mysite.com/blog).
I have a register/login feature in PHP site.
So what I want here is, whenever a member login in the main site using the login form, whenever he open the blog (mysite.com/blog), he shoulb be as logged in as the same user logged in the main PHP site.
In the same way, whenever a new user sign-up with the registration form in the main PHP site, he should become an user in the wordpress blog.

Thanks.

In your main site, you have to include WP’s functions by using wp_signon

define('WP_USE_THEMES', false); //this disables the theme
require('/blog/wp-blog-header.php'); //includes wordpress functions

And then, you can auto-login a user in WP by using

$credentials = array();
$credentials['user_login'] = 'example';
$credentials['user_password'] = 'plaintextpw';
$credentials['remember'] = true;
$user = wp_signon( $creds, false );
if ( is_wp_error($user) ) {
//login failed
echo $user->get_error_message();
}

This should work fine, I hope this helps you.
