title: How to unset entire array in PHP?
body: <p>I have a loop that runs 47 times on my page.  During the course of each loop, any error messages are entered into err[] and are printed out.  I'm trying to blank the array after each iteration and I'm running into some trouble.  </p>
  
  <p>There could be 4 or 5 error messages per iteration, sometimes none.  Is there an easier way of resetting the entire array after each iteration beyond running another foreach loop and unsetting each value?  A way of clearing all contents and resetting the indexes without actually removing the array itself?</p>
