回音“<pre>”以保留断点与断词的冲突

Question

我希望从文本列回mysql数据，并保留中断。我使用<pre>来做这件事，但是这会忽略style="word-break:break-word;"

伪示例：

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

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

( div中的文本是从mysql中提取的)

本例中的break-word;没有任何效果，因为文本是用<pre>标记包装的。如何保留原始文本的断行，但当我显示它时却引发一个单词中断？

Answer 1

使用nl2br函数。当新行可能出现时，它将添加<br/>标记。

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

Answer 2

您可以使用wordwrap将行喙插入到您的长字符串中，特别是当它们没有像您的示例那样的空格时。

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

Answer 3

试试这个；

<?php echo '<pre style="width:100px; word-wrap:break-word;">'; ?>
//some code
<?php echo '</pre>'; ?>
