How can PHP configuration settings like allow_url_fopen and display_errors impact the occurrence and handling of errors in PHP scripts, and what are common pitfalls to watch out for?

PHP configuration settings like allow_url_fopen and display_errors can impact the occurrence and handling of errors in PHP scripts. For example, setting allow_url_fopen to "Off" can prevent PHP scripts from opening remote files using functions like file_get_contents. Enabling display_errors can help developers quickly identify and fix errors by displaying them directly on the webpage. 

// To disable allow_url_fopen
ini_set('allow_url_fopen', 0);

// To enable display_errors
ini_set('display_errors', 1);
