What are some best practices for debugging PHP code in Wordpress plugins?

When debugging PHP code in WordPress plugins, it is important to enable WP_DEBUG in your wp-config.php file to display errors and warnings. You can also use functions like error_log() or var_dump() to output information for debugging purposes. Additionally, using tools like Xdebug or PHPStorm can help streamline the debugging process. 

// Enable WP_DEBUG in wp-config.php
define( 'WP_DEBUG', true );

// Use error_log() to output debugging information
error_log( 'Debugging info: ' . $variable );

// Use var_dump() to output variable information
var_dump( $variable );
