Answer 1

You need to be set data-html="true"

echo "<a data-content='(1)$var3array[0] <br /> (2)$var3array[1]<br />  (3)$var3array[2]'
        data-html='true'
        data-placement='bottom'>
    content
</a>"

Answer 2

You need to set data-html attribute to true and add
tag.

echo "<a data-content='(1)$var3array[0] <br />(2)$var3array[1] <br />(3)$var3array[2]' data-html="true" rel='popover' href='#' data-original-title='Notes'> Notes </a>';

Answer 3

您可以使用HTML <br>标签来归档它：

echo "<a data-content='(1)$var3array[0] <br /> (2)$var3array[1] <br /> (3)$var3array[2]' rel='popover' href='#'' data-original-title='Notes'> Notes </a>';
