1. JS-->PHP
a). JS create Json
1 <script> 2 $(document).ready(function(){ 3 /*--JS create Json--*/ 4 var jsonObject={}; // In another way: jsonObject={‘name‘:"Bruce",‘age‘:25}; 5 jsonObject[‘name‘] = "Bruce"; 6 jsonObject[‘age‘] = 25; 7 console.log(jsonObject); 8 console.log(‘This is stringfied json object: ‘ + JSON.stringify(jsonObject)); 9 console.log(JSON.parse(JSON.stringify(jsonObject))); 10 $("#demo").html(jsonObject.name + ", " +jsonObject.age); 11 /*--JS create Json--*/ 12 13 }); 14 </script>
b). Pass Json from JS to PHP by using Ajax
1 <script> 2 $(document).ready(function(){ 3 /*--JS create Json--*/ 4 var jsonObject={}; // In another way: jsonObject={‘name‘:"Bruce",‘age‘:25}; 5 jsonObject[‘name‘] = "Bruce"; 6 jsonObject[‘age‘] = 25; 7 console.log(jsonObject); 8 console.log(‘This is stringfied json object: ‘ + JSON.stringify(jsonObject)); 9 console.log(JSON.parse(JSON.stringify(jsonObject))); 10 $("#demo").html(jsonObject.name + ", " +jsonObject.age); 11 /*--JS create Json--*/ 12 13 /*--Ajax pass data to php--*/ 14 $.ajax({ 15 url: ‘php/test.php‘, 16 type: ‘POST‘, //or use type: ‘GET‘, then use $_GET[‘json‘] or $_POST[‘json‘] to in PHP script 17 data: { json: JSON.stringify(jsonObject)}, 18 success: function(response) { 19 console.log(response); 20 var jsonObj = JSON.parse(response); 21 $("#demo").html("From PHP‘s echo: " + jsonObj.name + ", " + jsonObj.age); 22 } 23 }); 24 /*--Ajax pass data to php--*/ 25 26 }); 27 </script>

2. PHP-->JS
a). PHP create Json
1 <?php 2 3 $arr = array( 4 ‘name‘ => "Bruce", 5 ‘age‘ => 25, 6 ); 7 echo json_encode($arr); // {"name":"Bruce","age":25} 8 echo $arr[‘name‘]; // Bruce 9 echo JSON_decode(json_encode($arr))->{‘name‘};// Bruce 10 echo implode((array)json_encode($arr)); // {"name":"Bruce","age":25} 11 12 ?>
b). PHP cURL Call RESTful web service

3. Pass Json from PHP to PHP (must be array then json_encode(‘json string‘)?)
http://stackoverflow.com/questions/871858/php-pass-variable-to-next-page
4. Submit parameters to PHP through HTML form POST/GET to download a file (e.g. Excel...)
I figure out a way around this. Instead of making a POST call to force the browser to open the save dialog, I will make a POST call to generate the file, then temporary store the file on the server, return the filename . Then use a GET call for this file with "Content-Disposition: attachment; filename=filename1". The GET call with that header will force the browser to open the "Save this file" dialog, always.
