How can specific text elements, such as making a word bold, be achieved in PHP email formatting?

To make specific text elements, such as making a word bold, in PHP email formatting, you can use HTML tags within the body of the email. For example, to make a word bold, you can surround it with <strong> tags. This will ensure that the word appears bold when the email is viewed by the recipient.

&lt;?php
$to = &#039;recipient@example.com&#039;;
$subject = &#039;Example Email&#039;;
$message = &#039;&lt;html&gt;&lt;body&gt;&#039;;
$message .= &#039;&lt;p&gt;This is an &lt;strong&gt;important&lt;/strong&gt; message.&lt;/p&gt;&#039;;
$message .= &#039;&lt;/body&gt;&lt;/html&gt;&#039;;
$headers = &#039;MIME-Version: 1.0&#039; . &quot;\r\n&quot;;
$headers .= &#039;Content-type: text/html; charset=iso-8859-1&#039; . &quot;\r\n&quot;;
$headers .= &#039;From: sender@example.com&#039; . &quot;\r\n&quot;;

mail($to, $subject, $message, $headers);
