Multidimensional array - duplicate of values through iterations - php

Question

I have started working with Magento, and I'm trying to get all custom options associated with a given product.
I've found a solution to that, however, I ran into issues.
My PHP-code:
foreach ($_product->getOptions() as $optionInfo) :
$values = $optionInfo->getValues();
foreach ($values as $values) :
$valuesArray[$values['option_type_id']] = array("option_type_id" => $values['option_type_id'], "option_id" => $values['option_id'], "title" => $values['title']);
endforeach;
$option = array("id" => $optionInfo->getId(), "type" => $optionInfo->getType(), "title" => $optionInfo->getTitle(), "values" => $valuesArray);
$options[$optionInfo->getId()]= $option;
endforeach;
It sure do return the correct information. Atleast in the first iteration:
[2] => Array
(
[id] => 2
[type] => drop_down
[title] => Custom option 1
[values] => Array
(
[4] => Array
(
[option_type_id] => 4
[option_id] => 2
[title] => Flaphack 1
)
[5] => Array
(
[option_type_id] => 5
[option_id] => 2
[title] => Flaphack 2
)
[6] => Array
(
[option_type_id] => 6
[option_id] => 2
[title] => Flaphack 3
)
)
)
However, during the second iteration (and perhaps even the third and forth and so on), I'm having duplicates of the values. In the second iteration, I'm getting the same values as i got in the first iteration PLUS the correct values for the second iteration:
[1] => Array
(
[id] => 1
[type] => drop_down
[title] => Custom option 2
[values] => Array
(
[4] => Array
(
[option_type_id] => 4
[option_id] => 2
[title] => Flaphack 1
)
[5] => Array
(
[option_type_id] => 5
[option_id] => 2
[title] => Flaphack 2
)
[6] => Array
(
[option_type_id] => 6
[option_id] => 2
[title] => Flaphack 3
)
[1] => Array
(
[option_type_id] => 1
[option_id] => 1
[title] => Flaphack 1.1
)
[2] => Array
(
[option_type_id] => 2
[option_id] => 1
[title] => Flaphack 1.2
)
[3] => Array
(
[option_type_id] => 3
[option_id] => 1
[title] => Flaphack 1.3
)
)
)
Do you guys have any idea what's going on? Would be greatly appriciated.

Try this code,
foreach ($_product->getOptions() as $optionInfo) :
$values = $optionInfo->getValues();
$valuesArray = array(); // added line
foreach ($values as $values) :
$valuesArray[$values['option_type_id']] = array("option_type_id" => $values['option_type_id'], "option_id" => $values['option_id'], "title" => $values['title']);
endforeach;
$option = array("id" => $optionInfo->getId(), "type" => $optionInfo->getType(), "title" => $optionInfo->getTitle(), "values" => $valuesArray);
$options[$optionInfo->getId()]= $option;
endforeach;
The $valuesArray is getting values in each iteration and you never cleared it. So when the outer foreach gets into second loop the $valuesArray gets values in incremental fashion. If you clear $valuesArray in each iteration of outer foreach you will get what you wanted.
