title: A few Q's about Bloom Filter implementation
body: <p>I recently discovered a site that set certain code kata.</p>
  
  <p>One of the Kata caught my eye and set me looking into Bloom filters.</p>
  
  <p>I'm using PHP and MySql.</p>
  
  <p>I have a table with roughly 45,000 words to act as a dictionary and i've written the code to create a bloom filter array.</p>
  
  <p>My questions are...</p>
  
  <ol>
  <li><p>At what point should the code run to create the Bloom filter array
  a) When the user access the page
  b) Every time a search is run
  c) Just once by me and then stored for future use
  d) something else entirely</p></li>
  <li><p>How should I store the array
  a) Keep it in an array
  b) Write to a text file
  c) Create a new table and store it there
  d) something else entirely</p></li>
  </ol>
  
  <p>Any help from someone experienced with bloom filters would be a great help.</p>
  
  <p>Cheers
