I found the way to synchronize them.
Instead of creating one LaunchDaemon, I created three. And LingOn was giving me problems with the program attributes for MySql, so I ended up editing them all in Text Wrangler. Here are my three LaunchDaemons located in /Library/LaunchDaemons on Mac OS X 10.6 with XAMPP 1.7.3
filename = xampp.startapache.plist<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>EnableTransactions</key>
<true/>
<key>Label</key>
<string>xampp.startapache</string>
<key>ProgramArguments</key>
<array>
<string>/Applications/XAMPP/xamppfiles/xampp</string>
<string>startapache</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>WorkingDirectory</key>
<string>/Applications/XAMPP/xamppfiles</string>
</dict>
</plist>filename = xampp.startftp.plist<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>EnableTransactions</key>
<true/>
<key>Label</key>
<string>xampp.startftp</string>
<key>ProgramArguments</key>
<array>
<string>/Applications/XAMPP/xamppfiles/xampp</string>
<string>startftp</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>WorkingDirectory</key>
<string>/Applications/XAMPP/xamppfiles</string>
</dict>
</plist>filename = xampp.startmysql.plistNote: On two lines it has xxx.yyy, which you should find in System Preferences / Sharing / File Sharing
If you are using XAMPP's FTP program, then you probably want to enable File Sharing and in Options enable AFP and possibly Windows sharing but disable FTP.
With these options set as described, on the File Sharing tab below where it says File Sharing: On, you will see
AFP://xxx.yyy/Replace xxx.yyy on the two below lines with what you find (i.e. xxx.yyy.pid and xxx.yyy.err) (e.g. mymac.home.pid)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>EnableTransactions</key>
<true/>
<key>Label</key>
<string>xampp.startmysql</string>
<key>Program</key>
<string>/Applications/XAMPP/xamppfiles/bin/mysqld_safe</string>
<key>ProgramArguments</key>
<array>
<string>--basedir=/Applications/XAMPP/xamppfiles</string>
<string>--datadir=/Applications/XAMPP/xamppfiles/var/mysql</string>
<string>--pid-file=xxx.yyy.pid</string>
<string>--log-error=xxx.yyy.err</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>WorkingDirectory</key>
<string>/Applications/XAMPP/xamppfiles/</string>
<key>UMask</key>
<integer>7</integer>
</dict>
</plist>With these three LaunchDaemons saved, restart your Mac. You should find all three services running when you log in again and open the XAMPP Control Panel.
Some may elect to add a key called "KeepAlive" that keeps the service running no matter what happens. I elected not to include this key because as a developer I may want to stop a service for a period of time as I do some maintenance and then restart it manually or have it restart automatically when I restart my Mac. I found that KeepAlive did just as described; I would manually stop the service and it would automatically start up again. Just thought I would mention it.
Hope this helps someone else.
Issue Resolved
