PHP Tips: How to send an email through a contact form to multiple recipients

Here is the simple line of code you can use to send a PHP email contact form to multiple email addresses:

  $to = $this->fields['EmailAddress'].',';
	  $to .='';

This comes in handy when you have to send the email to one specific email address in addition to an email address which is being pulled in via a variable – for example, if you want to send a copy of the email to users themselves, as in the example above.
