How to convert a string into a link in the VK API?

Question

API

Through the API, the wall.get method extracts JSON, which is then converted into a regular PHP array.
The echo $wall[$i]->text;text of the post received via the API is displayed.
The text may contain the following: [id*******|user_name, or how it is written in the post]
Question: how can I convert the above text so that when parsed on the site, the above text is also transformed into a link with a signature?

Answer 1

After receiving information through the API, use a regular expression to extract such text and convert it into links
