What potential issues or conflicts can arise when including multiple files in PHP?

One potential issue that can arise when including multiple files in PHP is namespace collisions, where two included files define functions or classes with the same name. To solve this issue, you can use namespaces to encapsulate your code and avoid conflicts. 

```php
// File1.php
namespace MyNamespace {
    function myFunction() {
        echo "Function from File1";
    }
}

// File2.php
namespace MyNamespace {
    function myFunction() {
        echo "Function from File2";
    }
}

// Main.php
include 'File1.php';
include 'File2.php';

MyNamespace\myFunction(); // Output: Function from File1
```

In this example, we use namespaces to define the functions in separate files without conflicts.
