title: is there a limit to zend framework's fetchAll method?
body: <p>so I was trying to use zend's fetchall function to retrieve all 194543 rows within a table...but then nothing came up and when I tried to debug the code, right during the fetchAll line, the debugger would just stop...</p>
  
  <p>is there actually supposed to be a limit to how many rows I can fetch with fetchAll and if so how do I overcome this limitation so that I can fetch everything and put it into a php variable?</p>
