• Answer:

  There is nothing like Async Tasks in Standard PHP. You could install pthreads or you have to work with some sort of a Queue. With a Queue it would work like that: Create a Mail-Send-Job Push that Job into a Queue (for example a Database) A third party programm (for example a cronjob) has to poll the Queue and execute the Tasks (send the Mail) if there are some Or like @Alan Machado said, use AJAX. So your page can load, and the Buttons sends an AJAX Request to the Server that sends the Mail.
