title: PHP regex remove space in specific string
body: <p>Im trying to remove the " " (space) in the following string. Be aware that this is only part of a string (there are valid spaces in it just not this one). So the code should identify this string then remove the space. </p>
  
  <p><strong>Example:</strong></p>
  
  <pre><code>18-Sep 00:20
  </code></pre>
  
  <p><strong>Test:</strong></p>
  
  <pre><code>/\d{1,2}-[a-z]{3}\s*( )\d{2}:\d{2}/
  </code></pre>
