I thank Mike Pavlak from  Zend and Alan Seiden from alanseiden.com for
sharing valuable points with me.
Step 1:   downloaded the IBM i Zend from :
http://www.zend.com/en/products/server/downloads
Step 2:  downloaded and installed XML Toolkit for IBM i update from:
http://www.zend.com/en/products/server/downloads
Note: The Toolkit demo programs will sometimes not work after the PTF is
applied. 
      Complete the following steps to overcome this issue:
    1. Stop Zend Server subsystems by entering:
       - GO ZENDSVR/ZSMENU ->option 5 ->option 2
    2. Start QSH shell by entering: 
       QSH
    3. Change to Toolkit directory by entering:
       cd /usr/local/zendsvr/share/ToolkitAPI
    4.  Run script by entering:
       ToolkitIpcrm.sh
    5. Press F3 to exit QSH shell
    6. Start Zend Server subsystems by entering:
       GO ZENDSVR/ZSMENU ->option 5 ->option 1
Now I can run the Toolkit programs from our IBM I server at:
http://samson:10088/ZendServer/Samples/Toolkit/
I recommend document:   PHP-Toolkit-from-Zend-and-IBM-2013.pdf  
Step 3:  learned much at  
http://youngiprofessionals.com/wiki/XMLSERVICE
Step 4:  viewed and listened to Alan Seiden's excellent presentation at:
http://www.zend.com/en/webinar/IBMi/70170000000bzBD-PHPToolkit-20130306.

in which Alan discusses the Toolkit extensively.
http://www.alanseiden.com/toolkit/  
Read document PHP-for-batch-taskes-on-IBM.pdf which is very informative.
Step 5:  got some remote support from Alan Seiden via email in which he
coached me on how to modify the Toolkit examples so I can run my own
programs and commands.
Step 6:  I have success at last in using PHP to run CL programs and IBM
commands on the IBM i.
