How can the presence of a BOM affect the parsing of JSON files in PHP?

The presence of a Byte Order Mark (BOM) at the beginning of a JSON file can cause issues when parsing the file in PHP, as it may not be recognized and could lead to errors. To solve this issue, you can use the `preg_replace` function to remove the BOM from the JSON string before parsing it. 

$jsonString = file_get_contents('example.json');
$jsonString = preg_replace('/^\xEF\xBB\xBF/', '', $jsonString); // Remove BOM
$data = json_decode($jsonString, true);

if ($data === null && json_last_error() !== JSON_ERROR_NONE) {
    die('Error parsing JSON file');
}

// Use $data as needed
