I have the following items previously configured:

• Macports install of PHP 5.2, MySQL, and Apache under /opt/local
• Zend Studio 8 with default workspace at /Users/stacey/Zend/workspaces/DefaultWorkspace7
• Zend Debugger installed (64-bit version)
• Running my Macbook in 64-bit mode

For a training class I am taking, I wanted to download and install the Zend Framework and create a new project. 

You can also, of course, use Zend Studio to create a new Zend Framework project.  This exercise is to understand how the Zend_Tool works, even without Zend Studio.

Here are the steps I needed to take to do so and also use my previously installed stack (rather than downloading Zend Server).

1. Download the latest version of Zend Framework from http://www.zend.com/community/downloads.  I downloaded Zend Framework 1.11 full
2. Extract the downloaded file.
3. Move the contents of the library directory to your php include path.  With my Macports install, this location is /opt/local/lib/php
4. Move the contents of the bin directory to your executable path.  For me this is /opt/local/bin
5. Create a symbolic link to the Zend Framework command line script (zf.sh)
   

   ln -s /opt/local/bin/zf.sh /opt/local/bin/zf

6. Test it out by typing the command below.  You should see a listing of options for the zf command.
   

   zf --help

7. You can configure the storage path for the Zend_Tool.  By default, it will create it in your $HOME directory, i.e. /Users/stacey.  I wanted to change this to store it with my Zend Studio files.  To do so, you need to add an environment variable like so:
   

   export ZF_HOME=/Users/stacey/Zend/workspaces/DefaultWorkspace7

8. Next type the following:
   

   zf --setup storage-directory
   
   zf --setup config-file
   
   zf --info

9. The last command (zf --info) shows the current setup for the Zend_Tool.  My results:
   

   shell$> zf --info
   
   Zend_Tool & CLI Setup Information
   (available via the command line "zf --info")
    * Home directory found in environment variable ZF_HOME with value /Users/stacey/Zend/workspaces/DefaultWorkspace7
    * Storage directory assumed in home directory at location /Users/stacey/Zend/workspaces/DefaultWorkspace7/.zf/
    * Config file assumed in home directory at location /Users/stacey/Zend/workspaces/DefaultWorkspace7/.zf.ini
   To change the setup of this tool, run: "zf --setup"

10. Note:  I also initially got the following warning:
    

    Failed loading opt/local/apache2/modules/ZendDebugger.so:  (null)

    
    To fix this, I first verified that I had the right version of Zend Debugger installed (64-bit for me).  This was fine and I verified it was loading by looking at phpinfo().  To get rid of this error, I needed to edit the zf.sh file. You will need a tool like TextWrangler to be able to save your changes.  Modify this line:
    

    "$PHP_BIN" -d safe_mode=Off -f "$PHP_DIR/zf.php" -- "$@"

    to
    

    "$PHP_BIN" -n -d safe_mode=Off -f "$PHP_DIR/zf.php" -- "$@"

    Save and restart Apache.
11. Next try creating a project.
    

    zf create project HelloWorld

    You should now see a HelloWorld directory in your Storage directory (for me this is /Users/stacey/Zend/workspaces/DefaultWorkspace7/).
