title: What does %S mean in PHP, HTML or XML?
body: <p>I'm looking at <a href="http://www.webmonkey.com/2010/02/php_and_mysql_tutorial_-_lesson_2">Webmonkey's PHP and MySql Tutorial, Lesson 2</a>.  I think it's a php literal.  What does <code>%s</code> mean?  It's inside the <code>print_f()</code> function in the while loops in at least the first couple of code blocks.</p>
  
  <p><code>printf("&lt;tr&gt;&lt;td&gt;%s %s&lt;/td&gt;&lt;td&gt;%s&lt;/td&gt;&lt;/tr&gt;n", ...</code></p>
