我有 2 个脚本，第二个脚本链接到第一个脚本，所以请同时查看这两个脚本。我的第一个脚本：主题.php
<?php

function bgchange(){
$bg = array('images/angel-beats-bg1.jpg', 'images/angel-beats-bg2.jpg', 'images/angel-beats-bg3.jpg'); // array of filenames
$i = rand(0, count($bg)-1); // generate random number size of the array
$selectedBg = "$bg[$i]"; // set variable equal to which random filename was chosen
return $selectedBg;
}
$bgUrl = bgchange();

当我运行status.php时，一切看起来都不错，但唯一的问题是背景没有显示，它只显示一个白页和内容本身。背景应该是来自天使节拍图片（每次刷新随机bg）。我的猜测是我在这一部分犯了一个错误：
body {
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-image: url('.$bgUrl.');
background-repeat: no-repeat;
margin: auto;
width: auto;
height: auto;
display: table;
text-align:center;
}
但我就是想不通我的错误。如何在status.php中显示背景？我真的很抱歉剧本太长了，我现在真的到了极限。
更新正如一些人建议的那样，我在浏览器中查看了status.php的源代码，得到了这个：
body {
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-image: url();
background-repeat: no-repeat;
margin: auto;
width: auto;
height: auto;
display: table;
text-align:center;
}
background-image: url();什么都没显示，救命！
在
函数 css（） 的开头添加global $bgUrl;
在第一段代码中，你有background-image: url('.$bgUrl.');，在第三段代码中，你有background-image: url('.$selectedBg.'); - 是哪一个？
此外，您可能应该将变量传递到函数中，以便您的代码如下所示：
编辑：
function css($bgUrl){
/* CSS code here*/
echo $bgUrl;
}
然后，当您调用该函数时，将变量传递给它：
css($bgUrl);
