PHP str_replace 无法正常工作 [英] PHP str_replace not working correctly

问题描述

我正在使用 str_replace 但它无法正常工作.我有一个文本区域，该区域与表单一起发送.当服务器收到数据时，我想将新行更改为，".

I'm using str_replace and it's not working correctly. I have a text area, which input is sent with a form. When the data is received by the server, I want to change the new lines to ",".

$teams = $_GET["teams"];
$teams = str_replace("\n",",",$teams);
echo $teams;

奇怪的是，我收到以下结果

Strangely, I receive the following result

切尔西

，真实

,巴塞罗那

而不是Chealsea，real，Barcelona.

instead of Chealsea,real,Barcelona.

怎么了?

推荐答案

为了扩展 Waage 的响应，您可以使用数组来替换两组字符

To expand on Waage's response, you could use an array to replace both sets of characters

$teams = str_replace(array("\r\n", "\n"),",",$teams);
echo $teams;

这应该可以正确处理这两个项目，因为单个 \n 是有效的，如果您只是替换 \r\n

This should handle both items properly, as a single \n is valid and would not get caught if you were just replacing \r\n
