What debugging tools or techniques can be helpful in identifying issues with PHP plugins?

When encountering issues with PHP plugins, using debugging tools like Xdebug or PHP's built-in error reporting can help identify the root cause of the problem. Additionally, enabling WP_DEBUG in WordPress can provide detailed error messages that can pinpoint where the issue lies within the plugin code. By carefully reviewing these error messages and using tools like var_dump() or print_r() to inspect variables and values, developers can effectively troubleshoot and resolve issues with PHP plugins.

php 
// Enable WP_DEBUG in WordPress to display error messages
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

// Use var_dump() to inspect variables and values
var_dump($variable);

// Use print_r() to display detailed information about arrays
print_r($array);
