"if if IE 9"在PHP中相当于？

Question

PHP语法中是否有PHP的等价物:

<!--[if lt IE 9]>
    <script src="/js/html5/html5shiv.js"></script>
<![endif]-->

？

Answer 1

使用本机php函数get_browser() ;

并阅读这篇文章.试试这段代码:

    $browser = get_browser();

    switch ($browser->browser) {
        case "IE":
            switch ($browser->majorver) {
                case 6:
                case 5:
                    echo '<link href="ie5plus.css" rel="stylesheet" type="text/css" />';
                    break;
                case 9:
                    echo '<link href="ie5plus.css" rel="stylesheet" type="text/css" />';
                    break;
                default:
                    echo '<link href="ieold.css" rel="stylesheet" type="text/css" />';
            }

            break;
}
