Logging errors and customizing php.ini rules

We can either display the coding errors in the browser or log them to a separate log file. It's at the preference of the developer, but I think logging the errors is the ideal solution for future reference. Also, sometimes we need to change the PHP configurations to make our code work. Many hosting servers will not allow you to directly edit the php.ini file, and hence we can use the wp-config.php file to override the default settings of the php.ini file.

Some hosting providers don't provide access to change the php.ini file, and you will have to request modification through server support.

Consider the following configuration rules for error logging with php.ini modifications:

@ini_set( 'log_errors', 'On' ); 
@ini_set( 'display_errors', 'Off' ); 
@ini_set( 'error_log', '/home/example.com/logs/php_error.log' ); 

First, we enable error logging in PHP and disable displaying errors in the browser by using the display_errors setting. Then, we define the path of the file where errors will be logged. You need to create this directory first and provide the necessary write permissions before this rule takes effect.

In this section, we had a brief overview of some of the most basic and advanced configurations in WordPress development. There are many other settings to help developers, as well as control features. You can take a look at the available configurations and their use in the WordPress codex at https://codex.wordpress.org/Editing_wp-config.php. Now, we have the complete setup to begin development tasks on top of WordPress.
