Question

I have this kind of array

Array ( [0] => Array (  [id] => 1 
                        [name] => PeopleOne
                        [address] => AddressOneOfPeopleOne 

        [1] => Array (  [id] => 2 
                        [name] => PeopleTwo 
                        [address] => AddressOneOfPeopleTwo 

        [2] => Array (  [id] => 3 
                        [name] => PeopleThree 
                        [address] => AddressOneOfPeopleThree 

        [3] => Array (  [id] => 4 
                        [name] => PeopleOne
                        [address] => AddressTwoOfPeopleOne 

and I want this kind of format

Array ( [0] => Array (  [id] => 1 
                        [name] => PeopleOne
                        [address] => Array(
                                    [0] => AddressOneOfPeopleOne
                                    [1] => AddressTwoOfPeopleOne
                        )

        [1] => Array (  [id] => 2 
                        [name] => PeopleTwo 
                        [address] => AddressOneOfPeopleTwo 

        [2] => Array (  [id] => 3 
                        [name] => PeopleThree 
                        [address] => AddressOneOfPeopleThree 

I don’t know how to do?
Could anyone please solve this?

I have a feeling this isn’t exactly what you’re looking for, but I’m not entirely sure what needs to be inside the final array. How is this, at least for a start?

<?php
$array = array(
array('id' => 1, 'name' => 'PeopleOne', 'address' => 'Address1'),
array('id' => 2, 'name' => 'PeopleTwo', 'address' => 'Address2'),
array('id' => 3, 'name' => 'PeopleOne', 'address' => 'Address3')
);


foreach ($array as $k => $v) {
$newarray[$v['name']][] = $v['address'];
}

echo '<pre>'.print_r($array,1).'</pre>';
echo '<pre>'.print_r($newarray,1).'</pre>';

?>
