How can the encoding of PHP files impact the functionality of array manipulation in PHP?

The encoding of PHP files can impact the functionality of array manipulation in PHP if the file is saved with an encoding that includes a Byte Order Mark (BOM). This can lead to unexpected characters being included in the output, causing issues with array manipulation functions. To solve this issue, save PHP files without a BOM or use functions like `utf8_encode()` to handle encoding properly. 

// Ensure the file is saved without a BOM or use utf8_encode() to handle encoding
$fileContents = file_get_contents('example.php');
$encodedContents = utf8_encode($fileContents);

// Now you can manipulate arrays without issues
$array = [1, 2, 3, 4];
// Perform array manipulation operations here
