计算JSON PHP中的对象数量？

Question

I have a JSON array and in that I have 3 JSON objects. I want to count the number of objects that is 3. but it is giving me 1. If I do not add the key "like", then it works. but after adding it, it is not working.

 $JSON = '{"like":['
            . '{"username":"suraj","password":"abc"},'
            . '{"username":"don","password":"abc"},'
            . '{"username":"rana","password":"abc"}'
            . ']}';


    $jsonInPHP = json_decode($JSON);
    echo count($jsonInPHP);

Answer 1

your json represent a object not a array. In your object you have like property which is an array so you need to right like this

count($jsonInPHP->like);
