What potential issues can arise when writing multiple data sets to a file in PHP without proper line breaks?

If data sets are written to a file in PHP without proper line breaks, the data will be appended consecutively without any separation, making it difficult to distinguish between individual data sets. To solve this issue, you should include line breaks after each data set to ensure readability and proper formatting. 

$dataSets = ["Data set 1", "Data set 2", "Data set 3"];

$file = fopen("data.txt", "a");

foreach ($dataSets as $data) {
    fwrite($file, $data . PHP_EOL); // Add line break after each data set
}

fclose($file);
