PHP无法将包含PHP代码的文件读取为文本文件 [英] PHP can't read files containing PHP code as text files

问题描述

我偶然发现了以下几种现象:

I've stumbled upon the following pecularity:

$ handle = fopen(realpath("../folder/files.php")，"r");

$handle = fopen(realpath("../folder/files.php"), "r");

无法读取文件，但是一旦我从文件中删除了php标签， 它变得可读，并且我的脚本在页面上打印非空文件内容. 另外，file.php从未执行过，所以我想知道为什么是这个问题.

can't read a file, but as soon as I remove php tags from the file, it becomes readable and my scripts prints non-empty file content on the page. Also, file.php is never ever executed, so I wonder why it is the problem.

我猜想Apache或PHP不允许以文本形式读取包含php标签PHP的文件.

I guess somehow Apache or PHP doesn't let read files containing php tags PHP as just text.

如何为特定文件启用它(在全球范围内这样做是不安全的)?

How can I enable it for my particular file (course doing it globally would be unsecure)?

使用PHP 5.2.x和Apache 2.0

Using PHP 5.2.x and Apache 2.0

推荐答案

我明白了.我当时使用Google chrome调试页面，并且意识到在查看源代码时，Chrome出于某些原因会隐藏PHP标签.我在Firefox上进行了相同的测试，查看源代码证明一切正常.

I got it. I was using Google chrome to debug the page, and I realized that when viewing the source, Chrome hides PHP tags for some reason. I ran the same test on Firefox, and viewing the source proved that everything was okay.

以下是测试详细信息:

代码:

$fh = fopen("test.php","r");
while ($line = fgets($fh)){
echo $line;
}

要读取的文件(test.php):

File to be read (test.php):

testing <?php testing2 ?> testing3

渲染(在Chrome和firefox上):

Rendering (on both Chrome and firefox):

testing  testing3

查看源代码(使用Firefox)

View source (using firefox):

testing <?php testing2 ?> testing3

查看源代码(使用Chrome-我的错误来源):

View source (using Chrome - source of my mistake):

testing  testing3
