You should not echo the result. Use the return statement to return the result of a method / function instead.

There are some issues with your code and one will be throwing a 'Recoverable Fatal Error'. Let's start with the call of the method:

1. You are passing in $data as a parameter but it hasn't been created (at least in the section of code posted). This would raise an E_NOTICE.
2. You are assigning a variable to a void method as no data is being returned by list_targets($data). If you later-on access it, it might give you unexpected results.
3. Possibility of mixing by-reference/by-variable: you pass in variable $data (as mentioned above not set before) and assign values to it using $data = $this->$json->results;. If no ampersand is preceding a parameter in a function definition (e.g. function returnByRef(&$varName)) the parameter cannot be changed within the function scope and will be the same as was passed in into the function.
4. Finally this line contains the error which is causing the exception:

• You are decoding the result of the result->getBody() and assign it to $json. This will now be an object, array or variable, depending on the returned data.
• in the next line you try to access the class instance scope's $this and try to access its property $json. Not only this, you are chaining a method call to it. This property hasn't been set (and I would strongly advise against 'variable variables' like $this->$property) so you are now calling a method on a non-object. The proper variable would have been the local variable $json.

Changed code

In fact you would only have to return the decoded JSON like so:

To be honest - and comments would be highly appreciated - I still wonder why this causes a 'could not be converted to string' error. Only idea would be that the raised exception is somehow trying to call __toString() on a non-object.
