How to turn off this error in wamp:
notice undefined offset
I'd like to turn of just this error, but not all errors.
There are two issues at work here. One is what errors PHP reports, and the second is whether or not it displays those errors on the page (as opposed to the apache error log). If you'd like to turn off just NOTICES:
<?php
error_reporting(E_ALL & ~E_NOTICE);
?>
If you'd like to report the notices to your error log but not display them to the user, do this:
<?php
ini_set('display_errors','off');
?>
Note that turning off display errors will stop displaying ALL errors to the end user, and you'll need to look at the error log, usually located in /var/log/httpd/error_log to see any errors while testing.
Have a look at error_reporting().
You could e.g. set the error reporting to
error_reporting(E_ERROR | E_WARNING | E_PARSE)
But better would be to actually check what is the cause of the Notice and fix it. Then you are on the save side.
E_NOTICE
Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script.
(If you can't fix the code...) You can exclude notices by setting an reporting level x & ~E_NOTICE, e.g.
<?php error_reporting( error_reporting() & ~E_NOTICE );
or in your php.ini (or similar)
error_reporting=E_ALL & ~E_NOTICE
php.ini => error_reporting = E_ALL & ~E_NOTICE
error->notice undefined offset
main thing is remove the error on your script.Programmer always wish to design program which is error free instead of error hiding.
The array vales are not set, so when PHP is trying to access the value of those array keys it encounters an undefined offset.
$new_array = array('1','2','3');//If I have an array
//We can now access:
$new_array[0];
$new_Array[1];
$new_array[2];
//If we try and access
$new_Array[3];
we will get the same error-->error->notice undefined offset
error_reporting(E_ALL);
ini_set('display_errors', 'On');
ini_set('html_errors', 'Off');
:D
Go to This direction on windows OS C:\wamp\bin\apache\Apache2.4.4\bin
Then open php.ini file by any editor recommended [sublime] in 514 line just paste this two lines.
;error_reporting = E_ALL error_reporting = E_ALL & ~E_NOTICE

I'm running ubuntu 10.04 + nginx + php-fpm 5.4
If I set display_errors = On in php.ini all errors are printed. If Instead I set that to off and then use ini_set('display_errors, '1'); directly in the script they will show as well but not the parse errors, just a blank page. I tried to play with error_reporting too and E_STRICT but I couldn't find a way!
If you disable display_errors in php.ini, and later enable it in your PHP script using ini_set(), it will only be enabled after the line containing that ini_set() call has been executed.
Parse errors occur before the PHP script even starts -- when the PHP file is parsed (hence the "parse error" name).
Which means they occur before your ini_set() has even a chance of being executed -- which means that, in your case, display_errors is not enabled when the parse error occurs ; and, as a consequence, you don't get anything displayed.
here I am years after this was answered, but I found a way around this.
For the script I'm writing, I created a second script which includes the ini_set() directives, followed by an include for the script I really am working on.
To with, here is test_run.php
<?php
ini_set('display_errors', '1');
ini_set('error_reporting', E_ALL);
include('./my_script.php');
?>
Aside from turning on display_errors, you can also watch error logs. Typically, running Ubuntu + apache, your error log is going to be in /var/log/apache2/error_log. To watch in real time what's happening, you run something like tail -f /var/log/apache2/error_log.
This can sometimes be more straightforward than fussing with php settings.

I have added ( un-commented ) the following lines, and the parse errors are being displayed now.
error_reporting
Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
Development Value: E_ALL
Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
Try error_reporting(E_ALL);. Or the docs
I'm having trouble turning off deprecated warnings for a short period of time. They're coming from a junk-pile script that I'm forced to work on for a while, wherein they use preg_replace with the /e modifier excessively. Rather than go and fix all the places that do this, it seemed like a better idea to turn off deprecated warnings while I'm working on it.
The problem, oddly enough, is that the error_reporting function at the beginning said script seems to have only an "On/Off" effect. That is, I can turn reporting fully off with error_reporting(0), and I can have it all on with something like error_reporting(E_ALL). But using any of the following options has no affect. I still get some 100+ deprecated warnings at the top of my page.
<?php
error_reporting(E_ALL ^ E_DEPRECATED);
error_reporting(E_ALL & ~E_DEPRECATED);
error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
I've verified that my php.ini file is set to E_ALL & ~E_DEPRECATED) (24575), and it shows as such in phpinfo(). The .htaccess file in the project root is empty. Why there even is one, I don't know.
PHP 5.5.9-1ubuntu4.4
Any ideas?
I would say there is probably another page or script that is being included that is setting error_reporting to a different value. You can call error_reporting() with no args to get the current value. Set it to something and check that the value hasn't changed after including other files.
error_reporting(E_ALL | E_STRICT);
just says "hey, log these kinds of errors/warning/notice"
I think you will need -
ini_set('display_errors', '0');
Try it out.
Solution :
ini_set("display_errors",'off');
Use this in your php script.It will hide warnings coming in your page.
Other interesting options for that function:
<?php
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);
// For PHP >=5.3 use: E_ALL & ~E_NOTICE
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
// Report all PHP errors
error_reporting(-1);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
?>

I am running Apache/PHP locally, and do receive errors in many cases, like uninitialized variables - but I have noticed a few cases where I do not receive error messages and am wondering if this is normal OR if I am missing out on anything,
<?php
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL);
$1a = "Hello world!";
echo $1a;
?>
Also producing no error:
<?php
ini_set('display_errors', 'On');
error_reporting(E_ALL);
function a()
{
$b = 5;
echo $b;
}}
a();
?>
Does this script product PHP errors as it should for you? If so, I am wondering why I receive none. This is not an error I am likely to make, but there have been other times where I receive a blank page like above, where I would like some sort of feedback.
Your calls to ini_set never get executed, because the error happens in the parsing phase (i.e. before anything gets executed). You need to set those configuration values earlier in .htaccess, httpd.conf or php.ini.
Open up php.ini, and CTRL-F for display_errors - is it set to on? When I installed php I used ini_set(); to try and see errors and it didn't work, but editing the php.ini file worked.
Edit: I looked at your phpinfo() output on the page you posted, and it's set to off. Turn it on if you can. If I recall correctly, you have to restart apache after you edit it.
Edit2: In your php.ini file, error_reporting should be set to E_ALL & ~E_NOTICE (default), E_ALL | E_STRICT (development), or E_ALL & ~E_DEPRECATED (production). Honestly, that's all gibberish to me - but if it helps, mine is set to E_ALL & ~E_DEPRECATED, and I recieved errors from your code.
I made a huge mistake by mixing result with results and it took me around 4 hours to finally find the bug.
So here is the question, in PHP, is it possible that I can enforce PHP to report errors if I use an undefined/uninitialized variable.
thank you
Set error reporting to E_ALL and ensure that display_errors in php.ini is on.
php.ini
display_errors = On
PHP code
// If you cannot access the php.ini file
// you can do this within your PHP code instead
#ini_set('display_errors' '1');
error_reporting(E_ALL);
The default setting you have right now probably excludes notices, the kind of errors PHP raises on uninitialized variables, which could be something like this:
error_reporting(E_ALL & ~E_NOTICE);
In a development environment I prefer using error_reporting(-1). Which reports all PHP errors.
yes, use error_reporting() and set it to E_ALL, like this:
error_reporting(E_ALL);
Set error reporting to report all errors. Either in php.ini or at runtime using error_reporting(E_ALL)
it already does report an error. something like this:
"Notice: Undefined variable: a in C:\wamp\www\testcenter\index.PHP on line 40"
maybe you didn't go specific enough. but you should try error_reporting(-1); as as if enforces the php to show some recomendations. a piece from the php manual about E_STRICT errors:
Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code.
just remember that error_reporting(-1); shows more errors than error_reporting(E_ALL); because E_STRICT errors are not included in the E_ALL constraint.
