    <para>
     Instead of lots of commands to output HTML (as seen in C or Perl),
     PHP pages contain HTML with embedded code that does
-    "something" (in this case, output "Hi, I'm a PHP script!").
+    "something" (in this case, output <computeroutput>Hi, I'm a PHP script!</computeroutput>).
     The PHP code is enclosed in special <link
     linkend="language.basic-syntax.phpmode">start and end processing
     instructions <code>&lt;?php</code> and <code>?&gt;</code></link>
