This just came up on #zftalk, and it appears that the information out there is either incomplete or incorrect, so I thought I’d just put out a simple solution.  Here’s a simple way to calculate the difference between two Zend_Date objects (in days):

$jan1 = new Zend_Date('1.12.2009', Zend_Date::DATES);
echo "\nJanuary first: ", $jan1->toString();

$christmas = new Zend_Date('25.12.2009', Zend_Date::DATES);
echo "\nChristmas is on: ", $christmas->toString();

$diff = $christmas->sub($jan1);
echo "\nNumber of days: ", $diff / 60 / 60 / 24;

This post is mostly a reminder to myself, but I thought I’d put it out there just in case other people wanted some help:

Installing Zend Server CE

If Zend Server is already installed, you need to remove it:

• For older versions of Zend Server:
  1. Run /Applications/ZendServer/bin/zendctl.sh stop
  2. Remove /etc/zce.rc
  3. Double-check that no instances are running (you can use ps ax|grep -i zend)
• For newer versions of Zend Server
  1. Run /usr/local/zend/bin/uninstall.sh

Now download the latest version of the Zend Server CE Installer and run the installer

Link the CLI binary so you can use PHP from the command line:

• sudo ln -s /usr/local/zend/bin/php-cli /usr/bin/php
• Please note that this step is optional

Installing the Zend Framework

Now download the latest version of the Zend Framework

Unzip and copy the following files:

• library/Zend to /usr/local/zend/share/ZendFramework/library/Zend
• extras/library/ZendX to /usr/local/zend/share/ZendFramework/library/ZendX
• bin to /usr/local/zend/share/ZendFramework/bin
• Please note that if you don’t need the zf command line tool, and the version of the Zend Framework that came with Zend Server is up-to-date, these steps are unnecessary

Finally, link the zf.sh file so you can access it easily:

• sudo ln -s /usr/local/zend/share/ZendFramework/bin/zf.sh /usr/bin/zf

That’s it for now.  Hope that helps someone else out.
