Doubt about include in files in previous directories [duplicate]

Navigation

Let's say I have a file called header.php located in CMS / admin / includes. Let's say I've included this header.php file in a file called index.php located in CMS / admin.

Inside the header.php file I want to give include in a file called functions.php which is in CMS / admin (the same directory as the index.php). I should use: 

<?php include "../functions.php" ?>

or just 

<?php include "functions.php" ?>

Since header.php is being included in a file (index.php) that is in the same functions.php directory (CMS / admin), I should give include as if functions.php were in the same directory of header.php?

Did you understand?

The current directory of the first one, index.php, is assumed in all other files.

You can use only <?php include "functions.php" ?> .

However, be aware of the include_path configuration directive.

To know what it contains in this directive, you can invoke the ini_get() function.

echo ini_get('include_path');

It is important to know that if an unforeseen event, an accident happens and you have another file "functions.php" in another directory that is in the "include_path", you can load an unexpected file.

It is safer to adopt absolute paths.
