How can you ensure proper line breaks are included when writing data to an EDI file using PHP?

When writing data to an EDI file using PHP, it is important to ensure that proper line breaks are included to adhere to the specific format requirements of the EDI standard. One way to do this is by using the PHP_EOL constant, which represents the correct end-of-line character based on the operating system. By appending PHP_EOL to each line of data before writing it to the file, you can ensure that the proper line breaks are included.

$data = "EDI data to write to file";
$file = fopen("edi_file.edi", "w");

// Append PHP_EOL to each line of data before writing to the file
fwrite($file, $data . PHP_EOL);

fclose($file);
