I don't like being warned

[marlin]

I copied a bunch of php scripts that have been working fine to a new computer. In all of the scripts I now get multiple warning messages complaining about undefined variables. They only serve to make the output ugly. The scripts have long been debugged; and still work properly, except for the messages..

I ran phpinfo.php which showed the error_reporting code to be 32765. I also inspected the php.ini file which included the directive

error_reporting = E_ALL ^ E_WARNING.

Finally, I inserted the command

echo 'error_reporting: '. error_reporting( ) ;

as the first line in one of my scripts; and the result was 32765. Now the code for all errors is 32767 and 2 for warnings. Thus 32767 - 2 = 32765.

So why are the warnings appearing?

I'm running the scripts on a windows laptop with the Abyss Web Server,

marlin,

PHP has several flavors of warnings. E_WARNING is only for a single kind of them.

You could be getting warnings about deprecation or other issues and these are not usually covered by E_WARNING.

Try setting in php.ini:

As I mention, the warnings are about undefined variables. It dawned on me that that is a good thing on my laptop, because that is where I debug programs and it's good to have undefined variables flagged because, although many are by design, some are typos I would want to know about.

The web hosting service where I upload scripts doesn't show warnings, which is just what I want.

That still begs the question of how to squelch warnings on my local machine.
