Как убрать ошибку warning

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

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

To suppress warnings while leaving all other error reporting enabled:

error_reporting(E_ALL ^ E_WARNING); 

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);

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

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

There is already answer with Error Control Operator but it lacks of explanation. You can use @ operator with every expression and it hides errors (except of Fatal Errors).

@$test['test']; //PHP Notice:  Undefined variable: test

@(14/0); // PHP Warning:  Division by zero

//This is not working. You can't hide Fatal Errors this way.
@customFuntion(); // PHP Fatal error:  Uncaught Error: Call to undefined function customFuntion()

For debugging it’s fast and perfect method. But you should never ever use it on production nor permanent include in your local version. It will give you a lot of unnecessary irritation.

You should consider instead:

1. Error reporting settings as mentioned in accepted answer.

error_reporting(E_ERROR | E_PARSE);

or from PHP INI settings

ini_set('display_errors','Off');

2. Catching exceptions

try {
    $var->method();
} catch (Error $e) {
    // Handle error
    echo $e->getMessage();
}
