Undefined Variable

[michael.davis]

Hi!  I have written some code to strip the weather forecast of a text file and it is working just fine.  In my error_log, I noticed the following errors:

 

[Wed Jul 11 12:56:25 2012] [error] [client 205.165.229.208] PHP Notice:  Undefined variable: state in /sync/public/intranet/ohx/tvwx/index.php on line 114

[Wed Jul 11 12:56:25 2012] [error] [client 205.165.229.208] PHP Notice:  Undefined variable: state in /sync/public/intranet/ohx/tvwx/index.php on line 117

 

Line 114 refers to $state == 0;

Line 117 refers to    if ($state == 0) {

 

I have this section in bold in my code.

 

Can someone point me in the right direciton to correct this?

 

Thanks!

Mike

 

My code is listed below:

Line 114 should be $state = 0

[psynor]

Argh you beat me to it KevinM1

 

Try to remove the excess = from $state == 0;
