HomeBackend DevelopmentPHP Tutorial页面效果显示有关问题

页面效果显示问题
服务器环境如下
window server 2012R2
IIS+PHP+MYSQL
基于PHPCMS的一个网站
问题如下:
页面中的一个按钮,在浏览器急速模式下,不显示,在兼容模式下,是可显示的

同样的网站代码,在本地部署以后,不管在急速模式还是兼容模式,都是能看到按钮
按钮样式代码如下

<br />.glyphicon {<br />    position: relative;<br />    top: 1px;<br />    display: inline-block;<br />    font-family: 'Glyphicons Halflings';<br />    font-style: normal;<br />    font-weight: normal;<br />    line-height: 1;<br />    -webkit-font-smoothing: antialiased;<br />    -moz-osx-font-smoothing: grayscale;<br />}

会是css代码的兼容性问题么?
对比了网页的源代码、css代码,都是一模一样,瞬间感觉无从下手了。。。
------解决思路----------------------
你分别用f12 进入调试模式进行调试呀。。。对比一下代码的区别就知道了。
------解决思路----------------------
先将按钮改成普通的。比如  .glyphicon{
   width: 100px; 
   height: 80px;
   background: red;
   ///先看这个在极速模式下的区别,再去一个一个添加你的这个按钮的样式代码,看看问题出在哪一行
   如果最普通的样式也会有这种情况,那说明你这个class 可能会与js有关联,导致不兼容。改个名字试一下,如果改了名字还不行,那就可能是其他的样式(比如它的顶层样式)影响到了。慢慢试一下吧。

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
