How can PHP developers ensure proper handling of line breaks and formatting when reading data from text files in different environments?

When reading data from text files in different environments, PHP developers can ensure proper handling of line breaks and formatting by using the `PHP_EOL` constant to represent the end of a line in a platform-independent way. This ensures that line breaks are handled correctly regardless of the operating system. Additionally, developers can use functions like `trim()` to remove any extra whitespace characters that may cause formatting issues. 

$file = 'data.txt';
$data = file_get_contents($file);

// Replace line breaks with PHP_EOL constant
$data = str_replace(["\r\n", "\r", "\n"], PHP_EOL, $data);

// Trim any extra whitespace
$data = trim($data);

echo $data;
