What potential issues can arise when using session_start() in multiple PHP files with similar code?

Potential issues that can arise when using session_start() in multiple PHP files with similar code include session conflicts, where multiple session_start() calls can overwrite or interfere with each other, leading to unexpected behavior or errors. To solve this issue, it is recommended to use session_start() only once in a central file and then include that file in all other PHP files where session variables are needed. 

// central_file.php

session_start();
```

Include the central file in other PHP files using:

```php
// other_file.php

include 'central_file.php';
