Simple answer... it is just a warning
When you first create a variable, you normally assign it a value. EG:
$MyVariable = "value";
However, you can (and quite often want to) not assign a value to the
variable before you use it. This is espically true in forms where the values
are sent by the user!
if ( ! empty( $MyVariable ) ) {
print "My Variable has the value of $MyVariable";
}
else {
print "My Variable is empty!";
}
would give you a notice warning 'Notice: Undefined variable: MyVariable in
blah blah blah on line 1. To remove this annoying feature, you will need to
edit the error reporting level in the php.ini file. Look in your php.ini
file for 'Error handling and logging'

[php.ini - what you are looking for]
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; error_reporting is a bit-field. Or each number up to get desired error
; reporting level
; E_ALL - All errors and warnings
; E_ERROR - fatal run-time errors
; E_WARNING - run-time warnings (non-fatal errors)
; E_PARSE - compile-time parse errors
; E_NOTICE - run-time notices (these are warnings which often
result
; from a bug in your code, but it's possible that it was
; intentional (e.g., using an uninitialized variable and
; relying on the fact it's automatically initialized to
an
; empty string)
; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
; initial startup
; E_COMPILE_ERROR - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR - user-generated error message
; E_USER_WARNING - user-generated warning message
; E_USER_NOTICE - user-generated notice message
;
; Examples:
;
; - Show all errors, except for notices
;
;error_reporting = E_ALL & ~E_NOTICE
;
; - Show only errors
;
;error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR
;
; - Show all errors except for notices
;
error_reporting = E_ALL & ~E_NOTICE

Subject: [PHP-INST] n00b - PHP on IIS 5 - Not Allowing File Writes Though
All Permissions Seem Correct
> Hi,
