Re-arrange a php array?

Question

I'm not even sure if we called transform, but, let's say we have an array like this:

A)

Array
(
    [id] => 532b436477936
    [name] => Record #1
    [created] => 20-03-2014
    [regions] => Array
    (
        [0] => Array
        (
            [id] => 532b3fcbf2353
            [name] => Region #2
            [created_at] => 1395343322
        )
        [1] => Array
        (
            [id] => 532b3fcbf2354
            [name] => Region #3
            [created_at] => 1395343323
        )
    )
)

And we wish to transform it like this:

B)

Array
(
    [0] => Array
    (
        [id] => 532b436477936
        [name] => Record #1
        [created] => 20-03-2014                
        [regions.id] => 532b3fcbf2353
        [regions.name] => Region #2
        [regions.created_at] => 1395343322
    )
    [1] => Array
    (
        [id] => 532b436477936
        [name] => Record #1
        [created] => 20-03-2014    
        [regions.id] => 532b3fcbf2354
        [regions.name] => Region #3
        [regions.created_at] => 1395343323
    )
)

Can I have some help with the code please?

$actual = array(
            'id' => '532b436477936',
            'name' => 'Record #1',
            'created' => '20-03-2014',
            'regions' => array(
                            array('id' => '532b3fcbf2353', 'name' => 'Region #2'), 
                            array('id' => '532b3fcbf2354', 'name' => 'Region #3')
                        )

        );

var_dump($actual);

$desired = array(
            array(
                'id' => '532b436477936',
                'name' => 'Record #1',
                'created' => '20-03-2014',
                'regions.id' => '532b3fcbf2353',
                'regions.name' => 'Region #2',              
                ),
            array(
                'id' => '532b436477936',
                'name' => 'Record #1',
                'created' => '20-03-2014',
                'regions.id' => '532b3fcbf2354',
                'regions.name' => 'Region #3',  
            )           
);

var_dump($desired);

Can I have some lights on were to look at in order to transform A, into B?

Loop through array A and just reassign to a new array, which will become B? I don't see how you can't achieve this... — Mr Pablo

It's not so much a transform you're looking for but a flatten stackoverflow.com/questions/9546181/… — Dave Goten

Thank you. @DaveGoten - I didn't know about the term flatten. Thank you. — MEM

$desired = array();
foreach($actual['regions'] as $region)
  {
    $desired[] = array(
            'id' => '532b436477936',
            'name' => 'Record #1',
            'created' => '20-03-2014',
            'region.id' => $region['id'],
            'region.name' => $region['name']);
  }

Try this:

$desired = array();
$basic = $actual;
unset($basic['regions']);
foreach($actual['regions'] as $key=>$val){
    foreach($val as $key2=>$val2) {
        $basic["$key.$key2"] = $val2;
    }
    $desired[] = $basic;
}
