How can PHP developers troubleshoot and fix errors related to CGI settings on their web hosting provider?

When PHP developers encounter errors related to CGI settings on their web hosting provider, they can troubleshoot and fix the issue by adjusting the CGI settings in their PHP configuration file. This can involve modifying the CGI variables such as `cgi.fix_pathinfo` and `cgi.force_redirect` to ensure compatibility with the hosting environment.

// Adjust CGI settings in PHP configuration file
ini_set('cgi.fix_pathinfo', 0);
ini_set('cgi.force_redirect', 0);
