Get inner array of multidimensional array

I have the following array:

 Array (
                [0] => Array 
                (
                    [example] => 'h'
                )
                [1] => Array 
                (
                    [example] => 'e'
                ) 
                [2] => Array 
                (
                    [example] => 'l'
                )
                [3] => Array 
                (
                    [example] => 'p'
                )
        )

And I am wondering how can I change this array to look like this instead.

Array( [example] => 'h', [example] => 'e', [example] => 'l', [example] => 'p')

I have tried using a nested foreach loop but using that I only get the values and not as an array.

There are a couple of ways to reach the values of a multidimensional array:

$array = array(
    0=>array('example'=>'h'),
    1=>array('example'=>'e'),
    2=>array('example'=>'l'),
    3=>array('example'=>'p')
);

1, If looping through the array:

foreach($array as $key=>$value){
    echo $value['example'];
}

2, Call a value directly:

echo $array[0]['example'];
echo $array[1]['example'];
echo $array[2]['example'];
echo $array[3]['example'];

It is impossible to create an array the way that you mentioned (having 4 'example' as keys). Take the following for example:

$array['example'] = 'h';
$array['example'] = 'e';
$array['example'] = 'l';
$array['example'] = 'p';
echo $array['example'];

The output would be p because you are simply overwriting the variable $array['example'] each time.
