- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我是 php 新手。我有一个网络表格。我在其中使用文本区域。我有另一个 PHP 页面,我在其中显示来自数据库的数据并应用 CRUD 操作。现在,当我单击“编辑”按钮时,问题是我的所有表单数据已从数据库中获取,但文本区域文本的格式已更改。它显示 \r\r\r\n
我使用 nl2br
但它不起作用。我想以相同的格式显示我的数据。
<textarea rows="20" cols="100" id="text" name="text" style="font-size:14px;" > <?php echo !empty(nl2br($text))?(nl2br($text)):'';?> </textarea><td>
我的整页代码是

最佳答案
您应该更改您的 php echo 代码,因为您不需要包含 !empty 验证。如果这样做,则必须在回显文本框之前创建它。我建议你将代码更改为:
<textarea rows="20" cols="100" id="text" name="text" style="font-size:14px;" > <?php echo nl2br($text);?> </textarea><td>
您还可以在这里找到 nl2br 的一些文档:
