Convert JSON to PHP

Question

Convert JSON to PHP

Is there a reliable standardized way of converting JSON on the server side? (Maybe JSONT)

Can you think about how to use XSLT for this or is there?

Edit: I should have been more specific. Some standardized conversion is what I'm looking for: using json_decode and json_encode does not do this, it converts between formats. What interests me is converting one JSON string to another.

PHP offers json_encode() , see the php manual on json_decode () .
If you get JSON values, you can decode them with json_decode() .
These functions require the installed JSON extension (which is the default).

JSONT is a client library for converting JSON data to HTML, to use it on the client web page to implement http://goessner.net/download/prj/jsont/jsont.js . You just need to pass it using a json object containing the information.

For example, if you want to add a link to this question:

 <div id="jsont-space"> <?php $jsontLink = new stdClass(); $jsontLink->uri = 'http://stackoverflow.com/questions/4656055/json-transformation-for-php'; $jsontLink->title = 'Question on Stackoverflow about: JSON transformation for PHP'; ?> <script type="text/javascript"> var transforms = { "self": "<a href=\"{uri}\" title='{title}'>{$.title}</a>" }; var data = <?php echo json_encode($jsontLink); ?>; document.write(jsonT(data, transforms)); </script> </div>

This, of course, is something very fast and dirty. But he must explain the whole option.

data definition
transformation definition
applying them to the page

here are some additional examples in JSONT (look @source)

Edit:
Added information about JSONT and an example implementation

 $my_array=array("first", "second", "third"); json_encode($my_array); //["first","second","third"]

As in php version 5.3, you can:

 json_encode($my_array, JSON_FORCE_OBJECT); // {"0":"first", "1":"second","2":"third"}

Well, it depends on what you want to convert. But, as Samuel says, the best choice for you on the right path is json_encode() or json_decode() , as this will allow you to convert an array or object to a JSON string or from a string to an object (using decoding)
