How can I convert php's POST variable to json format?
If this is entirely in php, and you simply want to convert the data in $_POST to JSON, you can do so like this:
$json = json_encode($_POST);
Using php's built-in function json_encode (doc)
If this is not what you want to do, please be more specific with your question.
json_encode($_POST);
Docs: http://php.net/manual/en/function.json-encode.php

I currently have json using json_encode from a mysql query which looks like this:
{"post_2":{"caption":"...","id":"...","accountID":"..","date":"07\/07\/2011 1:45:12 AM","title":"...","authorInfo":{"Email Address":"..."}}}, {"post_2":{"caption":"...","id":"...","accountID":"..","date":"07\/07\/2011 1:45:12 AM","title":"...","authorInfo":{"Email Address":"..."}}}
How can I have the json being an array of posts ('post_2', 'post_1') rather than it being a dictionary? The JSON will be decoded on an iPhone using SBJSON and the JSON will have to be made into an array in the backend.
Thanks in advanced.
Provide a non-associative array to json_encode(). The easiest way is usually to simply call array_values() on the (associative) array, and encode the result.
Take a look at PHP's json_decode function, specifically the 2nd parameter if you want an array.

i want to insert a json object to a mysql DB
You might be interested in json_encode().
On the other hand if you already got something json encoded then it already is a string and you can simply store it as-is in the database.
JSON itself is a string.
People use json_encode() and json_decode() to convert objects/arrays of PHP to string and back to objects/arrays.
$array = json_decode($json,true);
$string = implode(",",$array);
Now you can save this string in db as text.
Hi I have a JSON object that is a 2-dimentional array and I need to pass it to PHP using Ajax.Request (only way I know how). ...Right now I manually serialized my array using a js function...and get the data in this format: s[]=1&d[]=3&[]=4 etc. ....
my question is: Is there a way to pass the JSON object more directly/efficientely?..instead of serializing it myself?
Thanks for any suggestions,
Andrew
You can also use Prototype's function toJSON() to convert an array into a JSON object. After passing it to server via Ajax call, simply use PHP's function json_decode() to decode the object.
Pass the object as a JSON-string to PHP, and in PHP use the builtin json_decode to get a PHP-object from the string.
In Javascript, use a "stringify" function on your object to get it as a string, library available for example here: https://github.com/douglascrockford/JSON-js/blob/master/json2.js
In que Javascript side (with Prototye):
var myJSON= Object.toJSON(youArray);
In que Php side:
$myjson = $_POST['myjson'];
$arrayJSON= json_decode(stripslashes($myjson), true);
Check
http://www.openjs.com/scripts/data/ued_url_encoded_data/
to encode nested data directly correct, since Object.toQueryString() doesn't accept nested data...
