回显 '<pre>' 以保留中断与中断字的冲突答案

【问题标题】：Echoing '<pre>' to preserve breaks conflicts with break-word回显 '<pre>' 以保留中断与中断字的冲突

【问题描述】：

我想从 TEXT 列中回显 mysql 数据，并保留中断。我正在使用<pre> 来执行此操作，但这会忽略style="word-break:break-word;"

伪例子：

<?php echo '<pre>'; ?>
<div style="width: 100px; word-break:break-word">
LonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglong

LonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglong
</div>
<?php echo '</pre>'; ?>

（div里面的文字是从mysql中拉出来的）

break-word; 在这个例子中没有任何效果，因为文本是用<pre> 标签包裹的。 如何保留原文的换行符，但显示时会导致换行符？

【问题讨论】：

@Erhan Sönmez 的答案如下 - 它应该是 word-wrap: break-word;你有分词：break-word;

【解决方案1】：

使用nl2br 函数。当需要换行时，它将添加<br/> 标签。

<div style="width: 100px; word-break:break-word">
    <?php echo nl2br($yourVeryLongTextWithLineBreaks); ?>
</div>

【解决方案3】：

您可以使用wordwrap 将线喙插入到您的长字符串中，特别是如果它们没有像您的示例那样的空间

$longText = 'LonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglongLonglonglong';
echo wordwrap($longText, 8, "<br />\n",true);
