[thelist] json_decode

[Renoir B.]

Hello Bob

If your data is coming from a database you probably get the data as an
array already. Using doctine, it comes as an ArrayCollection object.

Then you can use JMSSerializer and add annotations and get it transformed
automatically as JSON objects using EventDispatcher in the Request/Response
cycle within Symfony2.

But if you are not using what I just mentioed and you have arrays. Keep
them as this as long as possible and use json decode only once.

An other detail is that you used

<?php
$obj = json_decode($json, true);
$result = $obj['0']->timezone;

Json_decode(JSON_STRING, true);

The true is for associative array. Not stdClass object.

Worse, var_dump() would tell you. Or var_export (not sure of the name).

Also, beware of the syntax.

$obj['0']

Will search for an associative array with a key as a sting 0.

Not the number.

PHP supports ['array','literal','notation'].  But, really is the same as
array('array,'...');

I hope it clarified things
