Do I have to initital all the variable?

[cindy]

Hi,

When I run my php scripts, I always get the warning messages such as "Failed opening" file name or "Undefined variable" or "Use of undefined constant", then the variable name. I don't recall I saw this problem before, only happened after the reinstallation of php. Is there somewhere I can change the set up (or ini ) file to get rid of these warnings? How do I get around of this?

Your help is very appreciated.
Thanks
Cindy

Error reporting levels are controlled by the error_reporting config directive in php.ini

You can also set it for each script you run, using the error_reporting() function.

For example...

<?php error_reporting(0); ?>

...turns all error reporting off.

The error reporting levels Max mentioned can also be changed in php.ini to affect the entire site. Additionally, the @ symbol suppresses function and variable warnings at runtime on a per call basis.

Regarding the "Use of undefined constant" and "Undefined variable" errors, these are often caused if you don't place associative array keys inside quotes. Making sure all your variables and array's are properly quoted should prevent these errors in the first place.

The answer to your question is mostly YES! If you try to open a file and you can't do it, don't you want to know that? The only exception I can see is getting form POST variables where unchecked boxes etc don't get sent.
