PHP - Calling a Class Method - php

Question

I've been handed a PHP class, and I'm not interested in fully restructuring it. (it works!)
But I'd like to add a slight modification inside a few methods.
Here is one of the many methods inside the class:
<?php
class SomeFunClass {
public function getAccountInfo()
{
$request = $this->prepareRequest('get_account_info');
$response = $this->execute($request);
return $response;
}
}
?>
The return $response is a string value.
I've come to a point that I need to return the $request string, which happens to be a json string.
The prepareRequest() method always returns a json string, which is then passed to the exec() method, which simply sends the data via cURL to a domain.
I'd like to extract the $request string (when I call the getAccountInfo() method), for later review.
Here's what I'm doing now:
<?php
$api = new SomeFunClass();
$curlresponse = $api->getAccountInfo();
?>
Obviously, the example immediately above only gives me back what the cURL response would be.
Would be nice to call a method that lets me see what the $request looks like.
I'm open to suggestions.

Answer 1

Just return an array with the request and the response:
<?php
class SomeFunClass {
public function getAccountInfo()
{
$request = $this->prepareRequest('get_account_info');
$response = $this->execute($request);
return array('request' => $request, 'response' => $response);
}
}
?>

Answer 2

You can modify those methods to store the last request into an attribute of the current class :
<?php
class SomeFunClass {
$last_request;
...
public function getAccountInfo()
{
$request = $this->prepareRequest('get_account_info');
$last_request = request;
$response = $this->execute($request);
return $response;
}
public function getLastRequest()
{
return $this -> last_request;
}
}
?>
Or, better, if prepareRequest is a method of yours, then just modify this one to store the last request.

You can do something like this:
<?php
class SomeFunClass {
public $request;
public $response;
public function getAccountInfo()
{
$this->request = $this->prepareRequest('get_account_info');
$this->response = $this->execute($this->request);
return $this->response;
}
}
?>
Now, you can do something like this:
<?php
$api = new SomeFunClass();
$curlresponse = $api->getAccountInfo();
$request = $api->request;
?>
Ideally, you can do implement your class like this to take actual advantage of OOP (so that these instance variables request and response are auto-set for all your methods):
<?php
class SomeFunClass {
public $request;
public $response;
public function getAccountInfo()
{
$this->prepareRequest('get_account_info');
return $this->execute();
}
public function anotherMethod()
{
$this->prepareRequest('another_method', 'some', 'args');
return $this->execute();
}
public function prepareRequest()
{
$args = func_get_args(); // contains your arguments
$method = array_shift($args); // contains your method name
...
...
$this->request = $return // value returned by this method
}
public function execute()
{
$request = $this->request;
...
...
$this->response = $return // value returned by this method
}
}
?>

You could also do this:
<?php
class SomeFunClass {
public function reviewRequest($request)
{
return $this->prepareRequest($request);
}
}
And then:
<?php
$api = new SomeFunClass();
$request = $api->reviewRequest('get_account_info');
