Insert this after all your variables are supposed to be declared in your 
web page.

Also newer versions of PHP complain about unintialized variables, older 
versions just kind of ignored that a variable wasn't set. If you have 
variables that might or might not have a value when the script is 
looking at them set them to blank at the top of the script eg.
$var1 = ""; //Only used sometimes.
$var2 = "Normal contents"; //Regular setting

Current PHP also changed the way certain variables are read so if you 
are using an older script you may have to look for variables related to 
file uploads and change them to use the newer syntax. All data related 
to file uploads is in the superglobal $_FILES
