php fopen相对路径断开-神秘 [英] php fopen relative path broken - mystery

问题描述

我知道必须进行某些更改"，但是我的代码似乎整夜无缘无故被破坏.

I know "something must have been changed" but my code seems to have broken over night for no reason.

我的服务器目录结构是这样的:

My server directory structure is something like this:

/
/脚本
/审核
/other_things

/
/scripts
/audit
/other_things

我在"scripts"文件夹中有一个脚本(假设它称为"/scripts/MyScript.php")，该脚本使用curl收集网页数据，并在审核"中保存所读取网页的带日期的副本. 文件夹.

I have a script (let's say it's called "/scripts/MyScript.php") in the "scripts" folder which gathers data from a webpage using curl, and saves a dated copy of the webpage it reads in the "audit" folder.

要写入审核文件夹，我使用了

To write to the audit folder, I used

$ fh = fopen("./audit/2008-09-09-183000.backup.log"，"w");

$fh = fopen("./audit/2008-09-09-183000.backup.log","w");

无论如何停止工作，都会抛出

however that stopped working, throwing

[function.fopen]:无法打开流:在第353行的/home/web/website.co.uk/audit/2008-09-09-183000.backup.log中没有此类文件或目录

[function.fopen]: failed to open stream: No such file or directory in /home/web/website.co.uk/audit/2008-09-09-183000.backup.log on line 353

不过，我通过将路径更改为

I have however fixed this by changing the path to

"../audit/2008等."来自"./audit/2008"(这是两个句号/句号，而不是一个)

"../audit/2008 etc." from "./audit/2008" (that's two full stops/periods, instead of one)

逻辑表明服务器配置必须有所更改，但是怎么办?这是我管理的专用服务器.我如何避免再次发生这种情况?

Logic dictates that something must have changed in the server configuration, but what? It is a dedicated server which I manage. How can I avoid something like this happening again?

我什至通过了MyScript.php的SVN，所有以前的版本都使用了single.在路径中.

I've even gone through SVN for MyScript.php and all previous versions have used the single . in the path.

推荐答案

使用dirname(__FILE__)获取当前文件的文件系统路径.然后从那里使用相对路径找到您的audit目录.

Use dirname(__FILE__) to get the filesystem path for the current file. Then use relative paths from there to locate your audit directory.

例如，在scripts/MyScript.php中，dirname(__FILE__)将返回/home/web/website.co.uk/scripts.您可以将/../audit可靠地附加到其上.

For example, within scripts/MyScript.php, dirname(__FILE__) will return /home/web/website.co.uk/scripts. You can reliably append /../audit to that.

(请注意，这甚至可以在include d或require d文件中使用，在这种情况下，它将返回包含的文件所在的目录).

(Note this even works in an included or required file—in that case it will return the directory in which the included file is located).
