PHP: Stop Notice and Variable Warnings in Error Log Files

I'm using PHP error logging in place of error displaying on production web sites. However, I do not want to see error messages about the use of uninitialized variables. I'd like to see all critical errors, except for notices and coding standards warnings. How do I disable error messages?

PHP provides various levels of error reporting using a bit-field as follows:


Error BitPurpose
E_ALLAll errors and warnings (doesn't include E_STRICT)
E_ERRORFatal run-time errors
E_WARNINGRun-time warnings (non-fatal errors)
E_PARSECompile-time parse errors
E_NOTICE Run-time notices (these are warnings which often result from a bug in your code, but it's possible that it was intentional (e.g., using an uninitialized variable and relying on the fact it's automatically initialized to an empty string)
E_STRICTRun-time notices, enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code.
E_CORE_ERRORFatal errors that occur during PHP's initial startup
E_CORE_WARNINGWarnings (non-fatal errors) that occur during PHP's initial startup
E_COMPILE_ERRORFatal compile-time errors
E_COMPILE_WARNINGCompile-time warnings (non-fatal errors)
E_USER_ERROR User-generated error message
E_USER_WARNING User-generated warning message
E_USER_NOTICE User-generated notice message

Show only errors

Open /etc/php.ini file
# vi /etc/php.ini

Set error_reporting as follows:

error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

Alternately, you can show all errors, except for notices and coding standards warnings

error_reporting = E_ALL & ~E_NOTICE

Save and close the file. Restart apache web server:
# /etc/init.d/httpd restart

If you are using nginx/lighttpd, try:
# service nginx reload
# service lighttpd restart

    I am running my web site on a shared host.
    In my case the /etc/php.ini is not accessible, but they allow me to use local php.ini in each folder.
    Other web hosting companies allow to modify .htaccess, so the alternative solution for this:

    error_reporting = E_ALL & ~E_NOTICE

    when using .htaccess is:

    php_value error_reporting 2039

    In the case where you have a shared host, the php.ini file needs to be recursively copied to each folder that will be executing PHP code.
    To automate this process, you can use this script:

    You could instead override the values of PHP configuration file “php.ini” inside your code by using the ini_set function , which has two parameters , one of them is the name of the configuration value ” for example ‘display_error’ ” and the other is the value we want to set it to ‘ 0 or 1 as an example for display_error’.

    in this case you don’t even need to restart the httpd , and you don’t affect other websites on a shared host

    copy and paste the below code just after your php opening tag in your code…

    error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
    ini_set(“display_errors”,”off”);
