Get value of JSON object in PHP variable

Question

I have the following JSON object:

[Object, Object, Object, Object, Object, Object, Object, Object, Object, Object]
 0: Object
 category: Object
 0: "Value"

I was wondering how I could get 'Value' in a variable in PHP. I thought category[0] would just do it but I get the following instead of 'Value':

 __proto__: Object 

What should I do?

• Mike Brant: Do you mean you have a javascript object (or array of objects it might appear) you want to pass to PHP? What you show is not JSON (JSON is nothing more than a serialization format). What is the actual mechanism proposed for passing the data (i.e. AJAX call)?
• Anoniem Anoniem: [{"category":{"0":"Value"} < You mean this?
• Tsanyo Tsanev: If that's how your JSON looks like it would be $var = json_decode($json); $var[0]['category']['0']
• Anoniem Anoniem: Mhm, I get 'null' instead of the value ..
• Tsanyo Tsanev: oh wait, try without the '' on the second 0 - $var[0]['category'][0]. Can you paste a larger snipped of your php code?

Answer 1

You have to converts the JSON string into associative array, which is done by json_decode() with second parameter set as true.

$var = json_decode($json, true); 
$value = $var['0']['category']['0'];
