php PHP在EOT中插入变量

PHP Inserting variable inside EOT

提问by Adrian M.

I want to insert a variable inside the EOT but is not working (I am new to php, maybe that's why). This code is part of a script, when I echo $usernamealone it shows the real name, but when I put it inside EOT is displaying plain text not the real name..

我想在 EOT 中插入一个变量但不起作用（我是 php 新手，也许这就是原因）。此代码是脚本的一部分，当我$username单独回显时，它显示真实姓名，但是当我将其放入 EOT 时，显示的是纯文本而不是真实姓名。

What am I doing wrong?

我究竟做错了什么？

$username=getUsername($ID);

echo <<<'EOT'

Some HTML code goes here

Hello $username, welcome back!

Some HTML code goes here

EOT;

You must leave out the single quotes here:

您必须在此处省略单引号：

echo <<<'EOT'

This denotes the 'nowdoc'variant, which doesn't interpolate variables.

这表示“nowdoc”变体，它不插入变量。

But you need the original "heredoc"syntax without quotes:

但是您需要不带引号的原始“heredoc”语法：

echo <<<EOT

$variable = 'text';
echo <<<EOT
Some {$variable} here
EOT;
