Number of elements in JSON

How can I find out the amount of elements of a json file through PHP.

See my example file: 

[{"descricao":"Fotografia","codigo":784},{"descricao":"Filmagem","codigo":789}]

I would like to check the amount of elements, which in this case should be 2, already tried to perform a json_decode before to try to manipulate json, but it always returns me a NULL. And with sizeof I just return the value 1.

Do the json_decode in the json string and use count in the result: 

$parseJson = json_decode('[{"descricao":"Fotografia","codigo":784},{"descricao":"Filmagem","codigo":789}]');
echo count($parseJson); // 2
