title: Exporting data from php to excel
body: <p>I need to export data from php (data retrieved from mysql database) to excel. I'm using Zend Framework. I need to do some changes to my data before exporting to excel. Actually, what I really need is to generate a monthly cash book. </p>
  
  <p>I have read a lot of documents, but ended up in a mess. I really can't understand how I should begin. Do I really need PEAR? Do I need to download any class library?Isn't there a simple way to do this?</p>
  
  <p>Thanks in advance</p>
