如何将包含内容作为字符串？ [英] How to get include contents as a string?

问题描述

可能重复：

执行PHP文件，并将结果作为字符串返回

PHP捕获打印/需要变量输出

我试图将include的内容添加到字符串中。这可能吗？

I am trying to get the contents of an include to a string. Is that possible?

例如，如果我有一个test.php文件：

For example, if I have a test.php file:

<?php
echo 'a is equal to '.$a;
?>

我需要一个函数，比如说include_to_string包含test.php并返回输出的内容在字符串中。

I need a function, say include_to_string to include the test.php and return what would be output by in in a string.

类似于：

<?php
$a = 4;
$string = include_to_string(test.php); // $string = "a is equal to 4"
?>

推荐答案

<?php

  ob_start();
  include 'test.php';
  $string = ob_get_clean();

我认为你想要的。请参阅输出缓冲。

I think is what you want. See output buffering.
