HTML into PHP Variable (HTML outside PHP code)
提问by Maksim Vi.
I am new to php and wondering if I can have something like this:
我是 php 的新手，想知道我是否可以有这样的东西：
<?php
...
magicFunctionStart();
?>
<html>
<head>...</head>
<body>...</body>
</html>
<?php
$variable = magicFunctionEnd();
...
?>
What I have to use right now is
我现在必须使用的是
<?php
...
$variable = "<html><head>...</head><body>...</body></html>"
?>
Which is annoying and not readable.
这很烦人且不可读。

Have you tried "output buffering"?
您是否尝试过“输出缓冲”？
<?php
...
ob_start();
?>
<html>
<head>...</head>
<body>...<?php echo $another_variable ?></body>
</html>
<?php
$variable = ob_get_clean();
...
?>

I'm not really sure about what you are trying to accomplish, but I think something like the heredoc syntaxmight be useful for you:
我不太确定你想要完成什么，但我认为像heredoc 语法这样的东西可能对你有用：
<?
$variable = <<< MYSTRING
<html>
<head>...</head>
<body>...</body>
</html>
MYSTRING;
However if you are trying to make HTML templates I would highly recommend you to get a real templating engine, like Smarty, Dwooor Savant.

Ok what you want to do is possible in a fashion.
好的，您想要做的事情以某种方式是可能的。
You cannot simply assign a block of HTML to a php variable or do so with a function. However there is a number of ways to get the result you wish.
您不能简单地将 HTML 块分配给 php 变量或使用函数来分配。但是，有多种方法可以获得您想要的结果。
- Investigate the use of a templating engine (I suggest you do this as it is worth while anyway). I use smarty, but there are many others
- The second is to use an output buffer.
- 调查模板引擎的使用（我建议你这样做，因为它无论如何都是值得的）。我使用smarty，但还有很多其他的
- 第二种是使用输出缓冲区。
One of the problems you have is that any HTML you have in your page is immediately sent to the client which means it cant be used as a variable in php. However if you use the functions ob_start and ob_end_fush you can achive what you want.
您遇到的问题之一是页面中的任何 HTML 都会立即发送到客户端，这意味着它不能用作 php 中的变量。但是，如果您使用函数 ob_start 和 ob_end_fush，则可以实现您想要的。
eg
例如
<?php
somesetupcode();
ob_start(); ?>
<html>
<body>
html text
</body>
</html>
<?php
//This will assign everything that has been output since call to ob_start to your variable.
$myHTML = ob_get_contents() ;
ob_end_flush();
?>
Hope this helps you can read up on output buffersin php docs.
希望这有助于您阅读php 文档中的输出缓冲区。

I always recommend to AVOIDbuffer functions (like ob_start,or etc) whenever you have an alternative (because sometimes they might conflict with parts in same system).
每当您有替代方案时，我总是建议避免使用缓冲函数（如ob_start, 或等）（因为有时它们可能与同一系统中的部件发生冲突）。
I use:
我用：
function Show_My_Html()
{ ?>
<html>
<head></head>
<body>
...
</body>
</html>
<?php
}
...
//then you can output anywhere
Show_My_Html();

Its REALLY CRAZY but be aware that if you do it :
它真的很疯狂，但请注意，如果您这样做：
<?php echo ""; ?>
You will get it:
你会得到的：
<html><head></head><body></body></html>
Keep calm, its only php trying turn you crazy.
保持冷静，它唯一的 php 尝试让你发疯。
