div function inside another div function

Question

Is it possible in php to make the second div appears inside the first one instead of getting two separated divs ? I would like to make a php dom system but I'm stuck with this problem.

This is the HTML I get when the page returns :

<div style="width:
                50px;
            height:
                30px;
            background-color:
                yellow;

                color:white
            ">
                blablabla
</div>
<div style="width:
                200px;
            height:
                50px;
            background-color:
                blue;

                color:white
            ">

</div>

This is the PHP code :

<? php

function genDiv($width, $height, $bgColor, $add, $content) {
    echo '
        <div style=\'width:
            '.$width.';
        height:
            '.$height.';
        background-color:
            '.$bgColor.';

            '.$add.'
        \'>
            '.$content.'
        </div>
    ';
}

$block = genDiv(
    '50px',
    '30px',
    'yellow',
    'color:white',
    'blablabla'
);
genDiv(
    '200px', 
    '50px',
    'blue',
    'color:white',
    $block
);

?>

You need to rewrite the function so it returns the HTML instead of echoing it out directly.

Then you can echo the result of the second call to the function.
