PHP: json_decode

Question

I have to parse values from a json string like this:

[{"type":"list","value":["A","B"],"field":"scheda"}] 

How can I do that using PHP function json_decode?

For example I want print:

field = "scheda"
values = "A,B"

Answer 1

$json = json_decode('[{"type":"list","value":["A","B"],"field":"scheda"}]');
print 'field = "'.$json[0]->field.'"'."\n";
print 'values = "'.implode(",",$json[0]->value).'"'."\n";

Answer 2

If you can't use json_decode(), why not try a class?

For instance, something like... http://www.phpclasses.org/package/4205-PHP-Serialize-and-unserialize-values-in-JSON-format.html
