title: In what scenario would I need 64bit php for large files or other uses?
body: <p>As I understand it from answers to my other questions on SO, 64bit php is good when you have very large numbers, use files larger than 2GB, or need more than 4GB or memory.</p>
  
  <p>My question is when would I need those things?  I want to use it for CRUD operations, a CMS, reports.  It is <em>possible</em> for me to have a missiion critical operation in the future.  I will be using a 64bit OS (Windows 2008 R2, Linux).</p>
  
  <p>I'm not even sure what it means for php to use a "file larger than 2GB."</p>
