内联PHP标记未关闭
[英]Inline PHP Tag not closing
问题描述
I have included php in html to change the background image according to some variables. 
我在html中包含了php来根据一些变量更改背景图像。 Thus i am calling img-set() function in body tag. 因此我在body标签中调用img-set()函数。 The function is working fine. 功能正常。 But the html code breaks after the function has been run. 但是在运行该函数后，html代码会中断。 I think it's some syntax problem not able to it figure out. 我认为这是一些无法弄清楚的语法问题。
<body style="background:url(images/<?php $obj->set_img();?>); -webkit-background-size: cover;-moz-background-size: cover;-o-background-size: cover;background-size: cover;">
The output in source code of web browser looks like: Web浏览器源代码中的输出如下所示：
<body style="background:url(images/music7.jpg
This break after displaying image name. 显示图像名称后中断。 Why so ?? 为什么这样 ？？
Here, is the set_img() function 这里是set_img（）函数
function set_img()
{
$ctr = date("d");
$arr7 = array("7","18","29");
$status = 0;
foreach($arr7 as $value){
if($ctr == $value){
echo "music7.jpg";
$status = 7;
}}
if(!$status) echo "music1.jpg";
}

There's probably a problem with your set_img() function causing the rest of the page to stop rendering. 你的set_img（）函数可能存在问题，导致页面的其余部分停止渲染。 Look at the code after you output the image. 输出图像后查看代码。 A quick test to see if the error is due to your function is to remove that php block and see if the page renders fine. 快速测试以查看错误是否是由您的函数引起的是删除该php块并查看该页面呈现是否正常。

I think there is an unrendered exception too. 我认为还有一个没有发现的例外。
But when I watch the set_img function, I cannot imagine how it could throw any exception. 但是当我观察set_img函数时，我无法想象它是如何抛出任何异常的。 May be $obj is not instanciate with the right class ? 可能是$ obj是不是与正确的班级同步？

Sounds like a silent PHP error. 听起来像一个无声的PHP错误。 It can be difficult to detect sometimes. 有时可能很难检测到。 Try checking your Apache error logs at /var/log/Apache2 and it should say what error is causing PHP to break. 尝试检查/var/log/Apache2的Apache错误日志，它应该说明导致PHP崩溃的错误。

I think you may be missing quotes around your url. 我想你的网址可能会丢失引号。 Try: 尝试：
<body style="background:url('imges/music7.jpg')">
