Undefined variables but no error generated

Hi, I have recently installed php 5.2.2.

Previously I was using version 4.x

In 4.x, if I accessed a variable that was not defined then I would get an error. But now I can have undefined variables and I get no error.

For example, If I put this line in my script
$a = $b;

Then i expect an error because $b does not exist.

My php.ini file contains the following settings which are the same as the php.ini that I used with php4.x

error_reporting = E_ALL & ~E_NOTICE
display_errors = On

So there must be some other switch to control this type of error detection and reporting.

Help appreciated.

Thanks.

An undefined variable generates a NOTICE level message. The error_reporting setting you posted specifically turns off notice level messages.

If you were receiving notice messages with that setting, then either the php.ini where that setting was located was not being used by php or there was another setting that was overriding that setting.

For your current want to display notice level messages, change the setting to: error_reporting = E_ALL

Stop and start your web server to get any changes made to php.ini to take effect.

change the setting to: error_reporting = E_ALL

Worked a treat. Too obvious. I dont know why I did not see it.

Thanks
