JSON is transferred between PHP and JS

1. js-->php

a). JS Create Json

1<script>2$ (document). Ready (function(){3         /*--js Create json--*/4         varjsonobject={};//in another way:jsonobject={' name ': "Bruce", ' age ':--};5jsonobject[' name '] = "Bruce";6Jsonobject[' age '] = 25;7 Console.log (jsonobject);8Console.log (' This is stringfied JSON object: ' +json.stringify (Jsonobject));9 Console.log (Json.parse (json.stringify (Jsonobject)));Ten$ ("#demo"). HTML (jsonobject.name + "," +jsonobject.age); One         /*--js Create json--*/ A          -     }); -</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         varjsonobject={};//in another way:jsonobject={' name ': "Bruce", ' age ':--};5jsonobject[' name '] = "Bruce";6Jsonobject[' age '] = 25;7 Console.log (jsonobject);8Console.log (' This is stringfied JSON object: ' +json.stringify (Jsonobject));9 Console.log (Json.parse (json.stringify (Jsonobject)));Ten$ ("#demo"). HTML (jsonobject.name + "," +jsonobject.age); One         /*--js Create json--*/ A          -         /*--ajax Pass data to php--*/ - $.ajax ({ theURL: ' php/test.php ', -Type: ' POST ',//or use the type: ' GET ', then use $_get[' json '] or $_post[' json '] into PHP script - data: {json:JSON.stringify (Jsonobject)}, -Successfunction(response) { + Console.log (response); -                 varJsonobj =Json.parse (response); +$ ("#demo"). HTML ("from PHP ' s echo:" + Jsonobj.name + "," +jsonobj.age); A             } at         }); -         /*--ajax Pass data to php--*/ -          -     }); -</script>

PHP Side

2. Php-->js

a). PHP Create Json

1<?PHP2     3     $arr=Array(4' Name ' = ' Bruce ',5' Age ' = 25,6     );7     EchoJson_encode ($arr);//{"name": "Bruce", "Age":8     Echo $arr[' Name '];//Bruce9     EchoJson_decode (Json_encode ($arr))->{' name '};//BruceTen     Echo implode((Array) Json_encode ($arr));//{"name": "Bruce", "Age": One      A?>

PHP Code

b). PHP CURL call RESTful Web Service

Coming soon

3. Pass Json from PHP to PHP (must is 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-a-around this. Instead of making a post call to force the browser to open the Save dialog, I'll 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 the header would force the browser-to-open the "Save this file" dialog, always.
