如何在Heredoc中打印粗体文本

Question

I have a block of Heredoc for email that I am sending out. In this block I am trying print selected text in bold/strong.

Take the following block of heredoc as an example.

<<<ENDINGTEXT

    Example text

    more text

    <b>This in bold</b>

ENDINGTEXT;

When I send above out as an email. The "b" tags do not convert the text within it to be bold. In the email it gets displayed as it is with b tags intact.

can someone please show me the way to achieve this as well some basic HTML integration in heredoc.

Answer 1

That is because the email which you are sending does not contain HTML enabled headers.

You need to set the headers like this.

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

For a detailed example, see the PHP Manual here
