------ Solution --------------------
JavaScript can be done, but most search engines do not execute js, so it is better to implement it in the background.
For example, first file get contents B .com/xxx to get the title and then set the title of a.com
------ Solution --------------------
Because it is an embedded iframe, the Javascript of website A has no permission to obtain the title of website B. It can only be updated in the background through php.
A can actively poll B on A regular basis, or B actively calls A's interface when the title changes
