Answer 1

你需要设置 data-html="true"echo "<a data-content='(1)$var3array[0] <br /> (2)$var3array[1]<br />&nbsp; (3)$var3array[2]'&nbsp; &nbsp; &nbsp; &nbsp; data-html='true'&nbsp; &nbsp; &nbsp; &nbsp; data-placement='bottom'>&nbsp; &nbsp; content</a>"

Answer 2

您需要将 data-html 属性设置为 true 并添加标签。echo&nbsp;"<a&nbsp;data-content='(1)$var3array[0]&nbsp;<br&nbsp;/>(2)$var3array[1]&nbsp;<br&nbsp;/>(3)$var3array[2]'&nbsp;data-html="true"&nbsp;rel='popover'&nbsp;href='#'&nbsp;data-original-title='Notes'>&nbsp;Notes&nbsp;</a>';请参阅此 stackoeverflow 问题

Answer 3

您可以使用HTML<br>标记对其进行归档：echo&nbsp;"<a&nbsp;data-content='(1)$var3array[0]&nbsp;<br&nbsp;/>&nbsp;(2)$var3array[1]&nbsp;<br&nbsp;/>&nbsp;(3)$var3array[2]'&nbsp;rel='popover'&nbsp;href='#''&nbsp;data-original-title='Notes'>&nbsp;Notes&nbsp;</a>';
