How to send an email?

Content

Hi,

I put the code below in a controller (code from http://documentation.custhelp.com/euf/assets/devdocs/august2016/Connect_PHP/Default.htm)

However I'm getting loads of errors. Any help?

<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message:  Use of undefined constant MOD_BUILD_VER - assumed 'MOD_BUILD_VER'</p>
<p>Filename: 3.3.3/optimized_includes.php</p>
<p>Line Number: 6966</p>

</div>
<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">
