title: php regular expression string replace
body: <p>I have a string like that as json response for a script:</p>
  
  <pre><code>"Lorem ipsum dolor sit amet, consectetur adipiscing elit, HTTP://unknown/string/in/unknown/place/ , sed do eiusmod tempor incididunt ut labore et dolore magna aliqua"
  </code></pre>
  
  <p>is there a way to replace <strong></strong> with an empty string using regular expression and php preg_replace?</p>
  
  <p>I'm not familiar with regular expression, could you just provide an example? I basically need to remove the substring starting with 'http' and finishing with a space, IF possible.</p>
  
  <p>thanks</p>
