PHP换行符Windows与Macintosh [英] PHP New line character Windows vs. Macintosh

问题描述

对于用户输入，我这样做: $var=str_replace(array('\r','\n'),'',$var);

For a user input I do this: $var=str_replace(array('\r','\n'),'',$var);

在Windows上运行良好，删除所有新行. 但是，在Mac(+ Firefox)上，它以某种方式用\字符替换了新行.

Works well on Windows, removing any new lines. However, on the Mac (+Firefox) it somehow replaces the new lines with a \ character.

关于发生这种情况的任何线索吗?

Any clues as to why that happens?

推荐答案

我很惊讶它可以在Windows上运行.

I'm surprised it works on Windows.

通常，要让PHP解释控制字符，它们必须用双引号引起来，例如

Usually, for PHP to interpret control characters, they need to be in double-quoted strings, eg

array("\r", "\n")
