How can text between two "+" be formatted as bold in PHP?

To format text between two "+" as bold in PHP, you can use the str_replace function to replace the "+" signs with the HTML <b> tags. This will wrap the text in bold formatting when it is displayed on a webpage.

$text = &quot;This is +bold+ text.&quot;;
$formatted_text = str_replace(&quot;+&quot;, &quot;&lt;b&gt;&quot;, $text);
$formatted_text = str_replace(&quot;+&quot;, &quot;&lt;/b&gt;&quot;, $formatted_text);
echo $formatted_text;
