Re: [DOC-NL] PHP variable

Thank you it works..........

This also works fine :

Its just a warning. It tells you that you are using a variable which has no
value. Just ignore the notice, or turn down error reporting to exclude
notices.

All it means is that the variable of $test which you have included in your
script HAS NO VALUE. If you were to write something lile
$test = "I Have A Value Now!";
then the 'error' message would disappear. Most of the time, you DO NOT WANT
to give a variable a value, such as when a user submits a form to your
script. The $Variables are filled by the user, not the php script. If the
user misses out a field, they would see the error message you mentioned.

To turn it off...
go to your php.ini
Search for
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
and change the line which looks like (Make sure there is no ; at the start
of the line, if there is then its the wrong line to change!)
error_reporting = E_ALL
to
error_reporting  = E_ALL & ~(E_NOTICE | E_USER_NOTICE) ; display all errors
and warnings
This will make php only show the errors which affect the running of your
scripts, not the notices such as 'Empty Variables'

Hope this helps
