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>
Js code create json array object
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>
JS side
1 <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 ?>
PHP code
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.
