Get values from Algolia JSON

Question

I have this piece of JSON and I need the FACETS.

I have managed to get the "nbHits" but I am struggling with getting the "facets"

$res = "the json below"

$res = json_encode($res);

$obj = json_decode($res);

print $obj->{'nbHits'}; /// 1116

I have tried

print $obj['facets']

and

print $obj['facets'][0]

I am missing something simple, any help is appreciated.

The JSON

Answer 1

The result is already json encoded format so why you're again encoding it?

To grab the no value on facets try this way $obj->facets->appt->no

$res = 'Your JSON goes here';
//-----Don't do again json_encode() again here
$obj = json_decode($res); 
print '<pre>';
print_r($obj);
print '</pre>';
echo $obj->facets->appt->no;

OR Make life easier by decoding it as an array

$array = json_decode($res,1); //see second parameter here
print '<pre>';
print_r($array);
print '</pre>';
echo $array['facets']['appt']['no'];
echo $array['facets']['hasOpened']['yes'];
