Remove warning messages in PHP

问题

I have some PHP code. When I run it, a warning message appears.

How can I remove/suppress/ignore these warning messages?

回答1:

You really should fix whatever's causing the warning, but you can control visibility of errors with error_reporting(). To skip warning messages, you could use something like:

error_reporting(E_ERROR | E_PARSE);

回答2:

You can put an @ in front of your function call to suppress all error messages.

@yourFunctionHere();

回答3:

To suppress warnings while leaving all other error reporting enabled:

error_reporting(E_ALL ^ E_WARNING);

回答4:

If you don't want to show warnings as well as errors use

// Turn off all error reporting
error_reporting(0);

Error Reporting - PHP Manual

回答5:

If you want to suppress the warnings and some other error types (for example, notices) while displaying all other errors, you can do:

error_reporting(E_ALL & ~E_WARNING & ~E_NOTICE);

回答6:

in Core Php to hide warning message set error_reporting(0) at top of common include file or individual file.

In Wordpress hide Warnings and Notices add following code in wp-config.php file

ini_set('log_errors','On');
ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Not exactly answering the question, but I think this is a better compromise in some situations:

I had a warning message as a result of a printf() statement in a third-party library. I knew exactly what the cause was - a temporary work-around while the third-party fixed their code. I agree that warnings should not be suppressed, but I could not demonstrate my work to a client with the warning message popping up on screen. My solution:

printf('<div style="display:none">');
    ...Third-party stuff here...
printf('</div>');

Warning was still in page source as a reminder to me, but invisible to the client.

回答8:

You could suppress the warning using error_reporting but the much better way is to fix your script in the first place.

If you don't know how, edit your question and show us the line in question and the warning that is displayed.

回答9:

I think that better solution is configuration of .htaccess In that way you dont have to alter code of application. Here are directives for Apache2

php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

I do it as follows in my php.ini:

error_reporting = E_ALL & ~E_WARNING  & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED

This logs only fatal errors and no warnings.

PHP 7.2 provides examples to try out. Here's a snippet of what is given within the php.ini file starting at line 449.

; Common Values:
;   E_ALL (Show all errors, warnings and notices including coding standards.)
;   E_ALL & ~E_NOTICE  (Show all errors, except for notices)
;   E_ALL & ~E_NOTICE & ~E_STRICT  (Show all errors, except for notices and coding standards warnings.)
;   E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR  (Show only errors)
; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
; Development Value: E_ALL
; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
; http://php.net/error-reporting
error_reporting = E_ALL

So give it try with any of these options. Once modified, restart your server and test out scenarios.
