简单封装一下php的打印

function dd($data)
{
    echo "<pre>";
    echo "<script>document.getElementsByTagName('body')[0].style.background = 'black'</script>";
    echo "<div id='div'>";
    var_export($data);
    echo "</div>";
    echo "</pre>";
    echo "<script>document.getElementById('div').style.color = 'red'</script>";
    die();
}
