Q: how to build an <ul>..<li> list on an array with php?

A: use the recursive function below for creation.

/**
 * @param array $aData
 * @return string $sMarkup Markup <ul>..<li> List
 */
function buildMarkupListTree($aData)
{
    if (false === is_array($aData))
    {
        return '';
    }

    $sMarkup = '<ul>';

    foreach ($aData as $sKey => $mValue)
    {
        $sMarkup.= '<li>' . trim($sKey);

        if (is_array($mValue))
        {
            $sMarkup.= buildMarkupListTree($mValue);
        }
        else
        {
            $sMarkup.= $mValue;
        }

        $sMarkup.= '</li>';
    }

    $sMarkup.= '</ul>';

    return $sMarkup;
}
