我知道PHP是服务器端的事情......但我想知道如何通过PHP得到用户的屏幕宽度。 我在网上搜索一下，他们说我必须使用JavaScript和PHP在一起。 但我不如何做的工作。 请告诉我，最简单的方法，通过PHP来获取用户的屏幕宽度。 如果可以通过JavaScript做才告诉我怎么去的JavaScript的宽度变量传递给整数格式（而不是字符串）的PHP变量。

推荐答案

不可能完全 PHP 您可能需要使用的JavaScript 太 反正试试这个

Not possible with complete php you might need to use javascript too Anyway try this

<?php
session_start();
if(isset($_SESSION['screen_width']) AND isset($_SESSION['screen_height'])){
    echo 'User resolution: ' . $_SESSION['screen_width'] . 'x' . $_SESSION['screen_height'];
} else if(isset($_REQUEST['width']) AND isset($_REQUEST['height'])) {
    $_SESSION['screen_width'] = $_REQUEST['width'];
    $_SESSION['screen_height'] = $_REQUEST['height'];
    header('Location: ' . $_SERVER['PHP_SELF']);
} else {
    echo '<script type="text/javascript">window.location = "' . $_SERVER['PHP_SELF'] . '?width="+screen.width+"&height="+screen.height;</script>';
}
?>
