我可以调用PHP方法异步运行吗？

Question

When a user views a certain profile page I need to send the end user an email but would like to do this asynchronously if at all possible. Can this be done with PHP? I really don't want to wait for the PHP function to complete before rendering the rest of the page. It should be seamless to the user.

Or is this a better solution from the client side:

$.post("msg.php?user=xxx", function(data) {
    ....   
}, "json");

Is there a preferred method?

Answer 1

If you want interactivity, go for the ajax() method; if you just want to hit a listener script (and thereby initialize a set piece of PHP functionality), use post() which is a short-hand version of the same method:

$(function() {

   // If you just want to activate a listener script (with no interaction)
   $.post('/path/to/script.php');

   // If you want to receive data back from your script for use in the DOM
   $.ajax({
      type: "POST",
      url: "/path/to/script.php",
      data: { name: "John", location: "Boston" }
   }).done(function( response ) {
      alert( response );
   });

});
