如何从PHP字符串中删除新行和返回? [英] how to remove new lines and returns from php string?

问题描述

一个php变量包含以下字符串:

A php variable contains the following string:

<p>text</p>
<p>text2</p>
<ul>
<li>item1</li>
<li>item2</li>
</ul>

我想删除此字符串中的所有换行符，以便字符串看起来像这样:

I want to remove all the new line characters in this string so the string will look like this:

<p>text</p><p>text2><ul><li>item1</li><li>item2</li></ul>

我尝试了以下操作但未成功:

I've tried the following without success:

str_replace('\n', '', $str);
str_replace('\r', '', $str);
str_replace('\r\n\', '', $str);

有人知道如何解决这个问题吗?

Anyone knows how to fix this?

推荐答案

您需要将\n用双引号引起来.
在单引号中将其视为2个字符，然后按'n'

You need to place the \n in double quotes.
Inside single quotes it is treated as 2 characters '\' followed by 'n'

您需要:

$str = str_replace("\n", '', $str);

更好的替代方法是将PHP_EOL用作:

A better alternative is to use PHP_EOL as:

$str = str_replace(PHP_EOL, '', $str);
