title: REGEXR help - how to extract a year from a string
body: <p>I have a year listed in my string</p>
  
  <pre><code>$s = "Acquired by the University in 1988";
  </code></pre>
  
  <p>In practice, that could be anywhere in this single line string. How do I extract it using regexr? I tried \d and that didn't work, it just came up with an error.</p>
