Save file at the same place as an included script

[luttkens]

I've got a script to access my database called mysql.class.php. So from every other script that is talking to the database, this file i included, like this for instance:

[PHP]<?php
include("../classes/mysql.class.php");
//Code using the included file goes here
?>[/PHP]

Now I want the file mysql.class.php to save a log-info for every query in a file that is placed in the same folder as the mysql.class.php-file. However, the file is saved where the script which included mysql.class.php is located.

How can I always save the file at the same place as mysql.class.php, even though it's included in another folder?

Can you not just point to the folder the same way you do with the include?

Personally, I would probably just set a constant that is pointed to the absolute location of the directory.

For example, if this were my index.php file:

<?php
// The absolute path where the index file is
define("LOC_ROOT_DIR", "/path/to/my/project/");
 
// The absolute path to the class directory
define("LOC_CLASS_DIR", LOC_ROOT_DIR . "classes/");
 
// Include the file.
include(LOC_CLASS_DIR ."class.mysql.php");
 
// Do whatever else you want with it here...
?>
 

And in my "class.mysql.php" file, I might do:

<?php
// After whatever you want logged, you could do:
file_put_contents(LOC_CLASS_DIR . "log.txt", $logText);
?>
 

Now, all you have to do is change the LOC_ROOT_DIR constant whenever you set this up on a new server (which usually doesn't happen that often) and you can use it in any script without having to worry about where the script is actually located.

Since I include the file from different locations, I can't do it the same way I do with the include...All paths are realative.

I could use a constant, but that's trouble when I'm uploading the site - and I do that quite often to fix bugs...
