based on accepted answer    output   some function      echo  output    if it results array then use json encode it will result json array which is supportable by javascript   output   some function      echo json encode  output     If someone wants to stop execution after you echo some result use exit method of php  It will work like return keyword   output   some function      echo  output  exit

Yes  the way you are doing it is perfectly legitimate  To access that data on the client side  edit your success function to accept a parameter  data     ajax       type   POST       url   somescript php       datatype   html       data  dataString      success  function data            doSomething data

It s an argument passed to your success function     ajax     type   POST     url   somescript php     datatype   html     data  dataString    success  function data        alert data               The full signature is success data  textStatus  XMLHttpRequest   but you can use just he first argument if it s a simple string coming back   As always  see the docs for a full explanation
