Are there any potential drawbacks or complications to consider when using relative paths in PHP scripts for links and redirects?

When using relative paths in PHP scripts for links and redirects, one potential drawback is that the paths may not work correctly if the script is included in different directories or if the file structure changes. To avoid this issue, it is recommended to use absolute paths or dynamically generate the correct path based on the current file location.

```php
// Dynamically generate the correct path based on the current file location
$currentDirectory = dirname(__FILE__);
$basePath = rtrim(str_replace($_SERVER['DOCUMENT_ROOT'], '', $currentDirectory), '/');
```
With this code snippet, you can dynamically generate the correct path based on the current file location, ensuring that links and redirects work correctly regardless of the file structure or directory in which the script is included.
