Include PHP file as string
提问by SnackerSWE
is it possible to make something like this?
有可能做这样的事情吗？
// file.php
$string = require('otherfile.php');
echo $string;
// otherfile.php
<!DOCTYPE html>
<html>
<head><title>Test</title></head>
<body>
<?php require 'body.php';?>
</body>
</html>
// body.php
<p>Lorem ipsum something</p>
And get this output?
并得到这个输出？
<!DOCTYPE html>
<html>
<head><title>Test</title></head>
<body>
<p>Lorem ipsum something</p>
</body>
</html>
I know that code won't work, but I hope you understand what I mean.
我知道代码行不通，但我希望你明白我的意思。

file.php
文件.php
ob_start();
include 'otherfile.php';
$string = ob_get_clean();
回答by Mark Baker
$string = file_get_contents('otherfile.php',TRUE);
echo $string
Use of the TRUE argument for file_get_contents() means it will search using the include path, like a normal include or require
对 file_get_contents() 使用 TRUE 参数意味着它将使用包含路径进行搜索，就像普通的包含或要求一样

Another cool thing to know, but SmokeyPHP's answer might be better:
另一件很酷的事情要知道，但 SmokeyPHP 的答案可能更好：
<?php
$var = require 'myfile.php';
myfile.php:
我的文件.php：
<?php
return 'mystring';

Yes, you can use a return statement in a file, and requires and includes will return the returned value, but you would have to modify the file to say something more like
是的，您可以在文件中使用 return 语句，并且 requires 和 includes 将返回返回的值，但是您必须修改文件以说出更像
<?php
return '<p>Lorem ipsum something</p>';
?>
check example #5 under include documentation http://www.php.net/manual/en/function.include.php
检查包含文档http://www.php.net/manual/en/function.include.php下的示例 #5

I need a solution for Joomla and dompdf and I found this solution
我需要 Joomla 和 dompdf 的解决方案，我找到了这个解决方案
ob_start();
require_once JPATH_COMPONENT . DIRECTORY_SEPARATOR . 'file.php';
$html = ob_get_clean();
only with require_once can use all functions from Joomla at the loaded script. The file.php is a .html file renamed to .php and where added php code.
只有 require_once 才能在加载的脚本中使用 Joomla 的所有功能。file.php 是一个 .html 文件，重命名为 .php 并在其中添加了 php 代码。
