php - php heredoc 出错

Question

我对 php heredoc 有疑问。我正在尝试做这样的事情。

$heredoc = <<<_HERE
This is the way
I try to use the
heredoc, but apparently
something is going wrong
_HERE;

显然我应该得到这个：

This is the way
I try to use the
heredoc, but apparently
something is going wrong

但我明白了：

这是我尝试使用heredoc的方式，但显然出了点问题

它没有格式化，主要思想是获取格式化文本。

有人能帮助我吗？

Answer 1

使用前置标签：

$heredoc = <<<_HERE
<pre>
This is the way
I try to use the
heredoc, but apparently
something is going wrong
</pre>
_HERE;

Answer 2

尝试

<?php
    $heredoc = <<<_HERE
This is the way
I try to use the
heredoc, but apparently
something is going wrong
_HERE;

    echo "<pre>";
    echo $heredoc;
    echo "</pre>";
?>
