推荐答案
当你在浏览器中运行 PHP 脚本时，默认情况下它会呈现为 HTML.如果您使用的书籍另有显示，则代码或插图不准确.您可以使用“查看源代码”查看发送到浏览器的内容，您将看到您的换行符存在.
When you run a PHP script in a browser, it will be rendered as HTML by default. If the books you’re using show otherwise, then either the code or the illustration is inaccurate. You can use “view source” to view what was sent to the browser and you’ll see that your line feeds are present.
<?php
echo "Line 1
Line 2";
?>
这将在您的浏览器中呈现为:
This will render in your browser as:
Line 1 Line 2
如果您需要向浏览器发送纯文本，您可以使用以下内容:
If you need to send plain text to your browser, you can use something like:
<?php
header('Content-type: text/plain');
echo "Line 1
Line 2";
?>
这将输出:
Line 1
Line 2
PHP Linefeeds ( ) Not Working 是指将输出发送到文件而不是浏览器.
PHP Linefeeds ( ) Not Working is referring to sending output to a file rather than the browser.
