PHP saying I have an undefined variable?

[bissatch@yahoo.co.uk]

Hi,

I get the following error:


Notice: Undefined variable: end_while in C:\Program
Files\Apache\Ap ache2\htdocs\cs p\inc\xmlmenu.p hp on line 102


This is a script that works on the server at work but it has difficulty
with me running on my home desktop. The variable, $end_while, is just a
basic variable. Is this a configuration problem where you can allow
undefined variables? Ive never had to define variables in the past.

Cheers

See: http://php.net/error_reporting

Example 1 shows how to turn it off. _BUT_ you shouldn't do that, fix the
code instead.

Re: PHP saying I have an undefined variable?

Note that this is not an error but a notice - there's a difference. Errors
will stop execution of your script, while warnings and notices are there to
inform you of possible faulty code. Depending on your error_reporting
setting in php.ini, you may or may not see warnings and notices. Your script
has an undefined variable on your server but your server is just not telling
you, because error_reporting is set to off or warn (not all).

It is likely that you are using $end_while in a conditional statement before
you have defined it, leading to the notice. You should set it to a default
value at the beginning of your script, or before you use it.

If you dont want to define the variable first - you can always use a
conditional to act if it doesnt exist:
if(!isset($varn ame))
{
do something
}
Or to supress the notices you can set the PHP error level reporting at
runtime using:
error_reporting (E_ALL ^ E_NOTICE);
That is; if you dont have access to your PHP.ini!
