php removes error message from a page

May 28, 2023 pm 07:39 PM

When using PHP to write a website, we may encounter some errors, such as syntax errors, variable errors or function errors in the code. These errors are often displayed directly on the page, affecting the aesthetics and user experience of the website.

In order to solve this problem, we need to remove all PHP error prompts on a page. Below, I'll cover some ways to achieve this.

  1. Turn off error reporting

PHP code generates error reports by default, and these reports are usually displayed directly on the page. We can use the following statement in PHP code to turn off error reporting:

1

error_reporting(0);

Copy after login

This statement will set the error reporting to the off state so that error information will not be displayed on the page. However, this method is not recommended as it just hides the problem and does not actually solve the error. When you need to debug code, you need to open error reporting to view error messages.

  1. Adjust PHP Configuration

We can also disable error reporting by changing the PHP configuration. In the php.ini file, you can find a line of code:

1

display_errors = On

Copy after login

Change it to:

1

display_errors = Off

Copy after login

This will turn off PHP error reporting on all pages. But this method only works with global settings. If you want to turn off error reporting on a certain page, you need to use other methods.

  1. Set error handler in code

In PHP code, we can use the set_error_handler() function to specify an error handler. This function takes a custom function as a parameter to handle errors in the code. For example, you can create a function that handles errors:

1

2

3

4

5

6

function customErrorHandler($errno, $errstr) {

    // 如果错误级别不是E_WARNING和E_NOTICE,就将错误输出到error.log文件

    if ($errno != E_WARNING && $errno != E_NOTICE) {

        error_log($errstr, 3, 'error.log');

    }

}

Copy after login

This function will output all errors with error levels set to other than E_WARNING and E_NOTICE to the error.log file. To enable this function, just use the following code in your code:

1

set_error_handler('customErrorHandler');

Copy after login

In this way, the error message will not be displayed on the page, but the error message will be output to the specified file.

  1. Using PHP Framework

If you are using a PHP framework, you can use the methods provided by the framework to disable error reporting. For example, in the Laravel framework, you can set debug to false in the app.php configuration file:

1

'debug' => env('APP_DEBUG', false),

Copy after login

This will turn off error reporting for the app. Similarly, other PHP frameworks can turn off error reporting through configuration files or code.

Summary

When developing a PHP website, error reporting may affect the user experience and aesthetics. This problem can be solved by turning off error reporting, changing the PHP configuration, setting up an error handler, or using a framework to disable error reporting. Please note that we need to turn on error reporting when debugging the code so that issues can be identified and resolved promptly.
