How to echo nested JSON object in php

Question

I'm trying to figure out how to echo the address1 out of the JSON below. I've tried this - echo "$arr->location[1]->address1<br>";, but it returns this error

Catchable fatal error: Object of class stdClass could not be converted to string in /home/benrud/public_html/student/webdesign/2016/02_benrud/tinker/data/index.php on line 202.

echo $arr; returns the JSON below.

Can you please format the outputted json correctly? It's hard to follow in its current state. — motanelu

Why are you doing $arr->location[1]? location is not an (numeric) array, it's an object. — gen_Eric

Location isn't an array, so I'd imagine just $arr->location->address1.

$arr = json_decode($json, true);

the true parameter makes sure it's an array and not an object

You must first decode then call the key so:

// Decode the JSON STRING
$arr = json_decode($arr, true); 
/*
 * first argument is the JSON STRING, 
 * Second sets the flag that the string is a dictionary 
 * (associative array)
 */

Now it is time to call the element. I put it in a conditional so to prevent errors

if (array_key_exists('address1', $arr['location'])) {
    echo $arr['location']['address1'];
}
else {
    echo "Array element Not Found. Here is what I have:\n\r";
    print_r($arr);
}

This Should return your element's value OR Dump the parsed PHP Array for review so you can edit the if statement to get the correct location.
