[jQuery] What is the best way to send data betwen JS -> PHP

[Aaron]

Hi, I use POST for send all data to a PHP scrip, for ex:

    data:"script.php?id="+id+"&text="+text,

but sometimes text contains \& or another istrange characters and not like
to be correct send data in this way.
¿what is the best way? PHP -> JS I use json, but for JS->PHP?
