title: Removing common words from a searched for string PHP
body: <p>OK, so I have a string of words delimited by space i.e.</p>
  
  <p>$commonwords = 'a,an,and,I,it,is,do,does,for,from,go,how,the,etc';</p>
  
  <p>And I receive a search query from $_POST['searchquery'];</p>
  
  <p>I want to remove any common words from the search string, what I am looking for as an end result will be more concise keywords that I can then use to query the database.</p>
  
  <p>So if the user searches for "How do I search for files"</p>
  
  <p>The string becomes "search files" when all common words are removed.</p>
