无法添加换行符.为什么会这样呢? [英] unable to add line breaks. Why is it so?

问题描述

以下脚本从名为arr的array打印字符串.从arr回显后，我尝试使用\n插入换行符，但看不到它.为什么会这样?

The following script prints the strings from the array named arr. After an echo from arr I try to insert a line break using \n but I don't see it. Why is that ?

<?php
$arr = array("ghazal","shayari","silence","hayaat");
echo $arr[0];
echo $arr[1];
foreach($arr as $var) {
  echo $var;
  echo "\n";
}

推荐答案

HTML相同地对待所有数字中的所有空白字符.

HTML treats all whitespace characters, in any number, identically.

也就是说，以下所有内容将在浏览器中呈现为单个空间:

That is, the following will all render as a single space in the browser:

echo "\n";
echo "\t";
echo "         ";
echo "  \n\n\n  ";

为了在HTML中呈现实际的 linkbreak ，您需要在文档中插入<br>元素.

In order to render an actual linkbreak in HTML, you need to insert a <br> element into your document.
