PHP正则表达式忽略“ S”字符

Question

我正在尝试使用php regex命令。我的字符串是

localhost / uploads / 125b77ed75d78dcba94f7527c9691c7b6cc20793 /

下面两行均返回“ 1”：

$dest = "localhost/uploads/125b77ed75d78dcba94f7527c9691c7b6cc20793/";
$res =  preg_match ( '/^localhost\/uploads\/*./' , $dest);

和

$dest = "localhost/uploads/125b77ed75d78dcba94f7527c9691c7b6cc20793/";
$res =  preg_match ( '/^localhost\/upload\/*./' , $dest);

regex命令似乎完全忽略了“ s”字符。我在这里想念东西吗？

预先感谢
