包含来自 PHP 流的代码

我想知道是否有可能创建一个流包装器，以便从数组中加载一些代码，并使用类似下面的内容

<?php include 'template://myarraykey/'; ?>

，并使其像从文件中执行正常包含一样工作？询问的原因是因为我真的不想在文件系统上存储模板，它们要么存在于内存缓存中，要么存在于数据库表中，并且绝对不想使用 eval()。

另外我假设我需要将allow_url_include 设置为on？

I'm wondering if it is at all possible to create a stream wrapper in order to load some code from an array into using something like the following

<?php include 'template://myarraykey/'; ?>

and have it work like doing a normal include from a file? The reason for asking is because I don't really want to store templates on the file system, they'll either exist in memcache or a database table and defiantly don't want to use eval().

Also I would assume I'll need to have allow_url_include set to on?

我知道这是一个老问题......但我认为值得注意的是，你可以这样做：

$content = '
  <?php if($var=true): ?>
    print this html
  <?php endif; ?>
';

通常这对评估来说非常麻烦，但你可以这样做：

include "data://text/plain;base64,".base64_encode($content);

它会像这样快速解析它！

I know this is an old question...but I think it's worth noting that you can do something like:

$content = '
  <?php if($var=true): ?>
    print this html
  <?php endif; ?>
';

Normally this would very cumbersome to eval, but you can do:

include "data://text/plain;base64,".base64_encode($content);

And it will parse it snappy like!

Include 可以采用任意 url。阅读此。下面是从那里获取的示例 HTTP 代码：

<?php

/* This example assumes that www.example.com is configured to parse .php
* files and not .txt files. Also, 'Works' here means that the variables
* $foo and $bar are available within the included file. */

// Won't work; file.txt wasn't handled by www.example.com as PHP
include 'http://www.example.com/file.txt?foo=1&bar=2';

// Won't work; looks for a file named 'file.php?foo=1&bar=2' on the
// local filesystem.
include 'file.php?foo=1&bar=2';

// Works.
include 'http://www.example.com/file.php?foo=1&bar=2';

$foo = 1;
$bar = 2;
include 'file.txt';  // Works.
include 'file.php';  // Works.

?>

只需将其更改为 include "template://$thevalue";

Include can take arbitrary urls. Read this. Here is an example HTTP code taken from there:

<?php

/* This example assumes that www.example.com is configured to parse .php
* files and not .txt files. Also, 'Works' here means that the variables
* $foo and $bar are available within the included file. */

// Won't work; file.txt wasn't handled by www.example.com as PHP
include 'http://www.example.com/file.txt?foo=1&bar=2';

// Won't work; looks for a file named 'file.php?foo=1&bar=2' on the
// local filesystem.
include 'file.php?foo=1&bar=2';

// Works.
include 'http://www.example.com/file.php?foo=1&bar=2';

$foo = 1;
$bar = 2;
include 'file.txt';  // Works.
include 'file.php';  // Works.

?>

And just change it to include "template://$thevalue";
