Displaying and Referencing a json_encode in Laravel - php

Question

I am not sure what the best method to display this is. I am creating an activity log for my website that is adaptable between different controllers. Here is my encode code:
$properties = [
'last_name' => $request->last_name,
'first_name' => $request->first_name,
'dob' => $request->dob,
'unique_id' => $unique_id,
'doctor_id' => $doctor->id
];
$log->properties = json_encode($properties);
However, properties on a different controller might have fields like revenue, address, etc, etc.
On the show page of my activity log controller, right now I am using {{$log->properties}} to display the object. It returns something like this output:
{"last_name":"Test4","first_name":"Test4","dob":"1984-09-13","unique_id":"Test4Test41984-09-13","doctor_id":19}
Ultimately, what I would like to do is have it display each of the object's items as a <strong> tag, then display the relative information. So, in simple html, the above properties would look like:
<strong>last_name:</strong> Test4<br>
<strong>first_name:</strong> Test4<br>
<strong>dob:</strong> 1984-09-13<br>
<strong>unique_id:</strong>Test4Test41984-09-13<br>
<strong>doctor_id:</strong> 19
Since the keys are different in each properties depending on what controller it was pulled from, I'm not sure how to display this. I even am having trouble finding out how to reference inside of the object. For example, {{$key->properties->last_name}} does not reference the last name. Neither does {{$key->properties()->last_name}}.

When you use json_encode to store the object inside $log->properties you are converting the object into a json string, that's because you can't use $key->properties->last_name, for this you can use json_decode in your $key->properties variable, then you will can access each property.
To display the data regardless of variable names you can do something like this:
$properties = json_decode($key->properties, true);
foreach ($properties as $key => $value) {
echo '<strong>'.$key.':</strong> '.$value.'<br>';
}
Or you can use blade to display this, the poin is that you need to convert your json to an array, then iterate over his keys and values.
