        'one'=>array(
            'value'=>'a',
            'color'=>'blue'
        )
    );
?>

<?php
    $basic_result = array(

    );
?>

i'm unable to create the logic

Use array_merge -

$basic_result = array_merge($basic, $more_basic)

OR +

$basic_result = $basic + $more_basic

You need to use array_merge

$basic_result = array_merge($basic, $more_basic);
print_r($basic_result);

you can set the value with the index name directly as shown below

<?php
    $basic = array(
        'one'=>array(
            'value'=>'a',
            'color'=>'blue'
        )
    );

    $basic['two'] = array(
        'value'=>'b',
        'color'=>'yellow'
    );    
?>

Well, PHP provides you a very clean solution for this kind of problem using array_merge()

Here, you have two options to solve your problem

1. $basic_result = $basic + $more_basic;
2. $basic_result = array_merge($basic , $more_basic);

In first case, the + operator appends elements of remaining keys from the right handed array to the left handed, whereas duplicated keys are NOT overwritten.

In second case, if the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended. If all of the arrays contain only numeric keys, the resulting array is given incrementing keys starting from zero.

It should also be noted that array_merge will return NULL if any of the arguments are NULL
