html - php 页面输出为什么换行符丢失了?

Jun 06, 2016 pm 08:25 PM
html php

<code><div>
<?php echo "abc";?>
</div>
</code>
Copy after login
Copy after login
Copy after login
Copy after login

<code><div>
<?php echo "abc";?>
</div>
</code>
Copy after login
Copy after login
Copy after login
Copy after login

为什么两种写法在页面输出会是同样地效果?第二个写法前显然要有个换行符啊.

<code><div>

</div>
</code>
Copy after login
Copy after login
Copy after login
Copy after login

为什么两种写法在页面输出会是同样地效果?第二个写法前显然要有个换行符啊.

说明 PHP 在解析 php 文件时 结束符 (?>) 后面如果是换行符, 会被忽略掉.

如果你想产生一个新行, 需要再多按一下回车.

html - php 页面输出为什么换行符丢失了?

最终页面的效果是一样的,HTML里的文本需要加<br>标签才能换行

建议LZ去看一下html的基础知识

这不管php的事,html <br>标签回车

换行得再加个换行符号<br>,其实不用在意这些细节的

html 解析时,忽略空格和回车

这是html的问题 你并没有加html的换行符啊 并不是你编辑器换行就能页面换行的

空格、换行,只会解析成一个空格符;<br>php中的\n只会把网页源码换行;<br>样式换行统一使用<br>
