How can the issue of the variable $newline="\n" not creating a new line in a file be resolved?

The issue of the variable $newline="\n" not creating a new line in a file can be resolved by using the PHP_EOL constant instead of "\n". PHP_EOL represents the end of line character appropriate for the operating system on which PHP is running, ensuring compatibility across different platforms. 

$file = fopen("example.txt", "w");
$newline = PHP_EOL;
fwrite($file, "This is line 1" . $newline);
fwrite($file, "This is line 2" . $newline);
fclose($file);
