【问题描述】：

我正在使用下面的代码。

<?
echo nl2br( 'The situation deteriorated into attacks on New York elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between 
Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.' , false  ) ;
?>

我得到如下输出

The situation deteriorated into attacks on New York elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between <br>
Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.

我想在没有<br> 的情况下获得输出，但此时我需要换行符（新行）。

【问题讨论】：

nl2br 的全部目的是添加
...如果您使用的是 nl2br，那么您有一个换行符。您可以使用“\n”在引号内插入换行符。
Blade: escaping text and allowing new lines的可能重复

【解决方案1】：

你为什么不能这样做..

<?
echo "The situation deteriorated into attacks on New York elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between\n Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.";
?>

有效吗？是的..回答..确定..他想要的答案..不确定..我们会看到他说什么..
为什么不呢？我可以看看你的代码吗？你有 2 个选择.. 换行 (
) 或换行 (\n).. 你不想要换行。
谢谢@Rick。我正在尝试echobladeLaravel 的模板文件中的输出。这是代码<div class="col-xs-12">{{nl2br($story->note)}}</div>。谢谢
对不起..我只是没有关注..您是否希望将文本字符串分成 2 行？
我想把那串文本分成两行。

【解决方案2】：

试试这个。顺便说一句，我不知道字符串后面的“false”是什么，但如果你在代码中删除它，它工作得很好，我看不到 html 换行标记。

<?php 
$string = 'The situation deteriorated into attacks on New York elite,followed by attacks on black New Yorkers and their property after fierce competition for a decade between Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.';
function nl2br2($string) { 
$string = str_replace(array("\r\n", "\r", "\n"), "<br />", $string); 
return $string; 
} 
echo"$string";
?>
