retrieving json data and cache it for future reference

[php_begins]

My function returns a bunch of attribute ids and it's corresponding names in json format. For eg:

 

 

  {
        "DETAILS": [
            {
                "ATTR_ID": "522",
                "ATTRIBUTE_ID": "4222",
                "ATTRIBUTE_TYPE": "email",
    
            },
            {
                "ATTR_ID": "523",
                "ATTRIBUTE_ID": "4006",
                "ATTRIBUTE_TYPE": "interest",
    
    
            }
        ]
    }

 

I need to store it in an array which i need to cache .( I'll be probably using $_SESSION)

 

Now another function returns me set of attribute ids:

 

 

  $val_array = $subarray[arrayOfAttributes];
    	foreach ($val_array as $val)
    	{
    		print "Attrib Value: $val\n"; //This will print ids 4222,4223,etc
    	}

what I need to do is correspond the ids with the type from the cache nad print out the respective Types.

I am unable to formulate this logic into code.

First of all you'd want to use json_decode () to get that array of yours.

Next is to loop through it, and check if the attribute_id is in the $val_array. If it is, then you know you can print it to screen.
