title: PHP best way to MD5 multi-dimensional array?
body: <p>What is the best way to generate an MD5 (or any other hash) of a multi-dimensional array? </p>
  
  <p>I could easily write a loop which would traverse through each level of the array, concatenating each value into a string, and simply performing the MD5 on the string. </p>
  
  <p>However, this seems cumbersome at best and I wondered if there was a funky function which would take a multi-dimensional array, and hash it.</p>
