  <p>I am using php and have string with content = </p>
  
  <p><code>&lt;a href="www.something.com"&gt;Click here&lt;/a&gt;</code></p>
  
  <p>I need to get rid of everything except "www.something.com"
  I assume this can be done with regular expressions.
  Any help is appreciated!
  Thank you</p>
