Remove `=\n` From Html

For example in your HTML tags, the = is encoded as =3D if you take a closer look at it.

To decode the message back to normal HTML, you must apply quoted_printable_decode() to the string.

$msg_body = quoted_printable_decode($msg_body);

\n
\r
\r\n

You can also use regexp, if you know that there is only selected number of markup that have the issue:

$msg_body = preg_replace('/(\w+)=[\s\r\n]*/', '$1', $msg_body);

In your case, it should transform the </td= ...> into <td>
