Unset variables expected to be set

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Change /private/etc/php.ini to report notices (fx error_reporting  =  E_ALL 
| E_STRICT)
2. Try to use the app

What is the expected output? What do you see instead?
It is expected to work. Instead, a lot of undefined-errors occur on the page 
(Especially 
$extension in iPhone Remote.app/Contents/Resources/www/common/filerow.php on 
line 46 
and $show_arrow in iPhone Remote.app/Contents/Resources/www/common/filerow.php 
on line 
85.

What version of the product are you using? On what operating system?
iPhone Remote 0.9.21 on OS X 10.5.2.

Please provide any additional information below.
Changing the php.ini is not an option for me, as the machine is used for 
web-development.
The errors are a result of unsafe programming anyhoo, as it should always be 
ensured that a 
variable exists before using it (by the use of isset()).
