在Joomla中获取文件内容

[英]Get file contents in Joomla

原文 2014-07-01 14:32:38 6 2 php/ linux/ file/ joomla/ permissions

I'm trying to get a file's content into a variable but I don't get anything when I read the file. 我正在尝试将文件的内容放入变量，但读取文件时却什么也没得到。 I used both methods JFile::read() and file_get_contents() but both return the same thing: a blank string, not an error , not any boolean values or anything. 我同时使用了JFile::read()和file_get_contents()这两种方法，但是都返回了相同的东西：一个空字符串，不是一个错误，没有任何布尔值或任何东西。

I want to mention that I'm working on a Linux machine (just for 2 days) and recently I changed the permissions for the entire machine to 777 ( I don't know if this affects something or not). 我想提到的是，我在Linux机器上工作（仅2天），最近我将整个机器的权限更改为777（我不知道这是否会影响某些事情）。

Is the a connection between my OS, permissions and the php's file_get_contents() ? 我的操作系统，权限和php的file_get_contents()之间是否存在连接？ or Joomla restricts file reading? 或Joomla限制文件读取？

Also I want to mention that my file_get_contents() function was added manually by me in the index.php file , also the file I want to read was manually added in the same folder with index.php . 此外，我想提一提我file_get_contents()函数手动添加由我在index.php文件，我也想读取文件在同一文件夹中手动添加index.php 。
