不同的操作系统有不同的符号，如何写PHP代码使我们可以在不同操作系统中可移植？
1、DIRETORY_SEPORATOR 当前操作系统默认的文件路径分隔符
$unixpath = "/var/test/a.php": //在unix系统下必须使用"/"作为文件路径分隔符
$windwospath1 = "C:\\www\\test\\aa.php": //windows系统下默认使用"\"作为文件路径分隔符，但是还是需要"\"将其转义
$windowspath2="www/test/a.php" //推荐使用这种
为了程序的可移植性，建议文件路径都是用"/",也可以使用DIRETORY_SEPORATOR
2、PHP_EOL 当前系统的换行符
windows下 \r\n表示换行符
unix系统下\r表示换行符
