How to enable all error reporting in php? Method introduction

In the process of writing PHP scripts, you often encounter various errors, including syntax errors, runtime errors, logic errors, etc. In order to better troubleshoot and debug these errors, we need to enable PHP's error prompts and reporting functions.

PHP provides multiple error reporting levels, including E_ERROR, E_WARNING, E_PARSE, E_NOTICE, and more. Among them, E_ERROR represents a fatal error that will cause the script to stop running immediately. E_WARNING indicates a non-fatal error and will not stop the script immediately. E_NOTICE represents some non-fatal runtime errors such as undefined variables and calls to undefined functions.

By default, PHP's error reporting level is E_ALL & ~E_NOTICE, that is, all errors are reported, but notification-level errors are ignored. If we want to enable all error reporting, we can set the error reporting level to E_ALL.

The following are several ways to turn on all error reporting in PHP:

1. Turn on error reporting in the code:

We can add the following at the beginning of the code Statement:

error_reporting(E_ALL);

This means that we set all error reporting levels to E_ALL, that is, report all errors.

2. Enable error reporting in the php.ini file:

We can edit the php.ini file directly and add the following code to it:

error_reporting = E_ALL

3. Turn on error reporting in the .htaccess file:

When using the Apache server, we can add the following directive in the .htaccess file:

php_flag display_errors on
php_value error_reporting E_ALL

This directive means to open error message, and set the error reporting level to E_ALL in the directory where this file is located.

Summary:

It is very necessary to enable all error reporting in PHP. During the development process, we will receive timely prompts when encountering errors, allowing us to better troubleshoot and modify the code. The above are three methods, which are suitable for different scenarios. You can choose the method that suits you according to your needs.
