How can the configuration settings in php.ini and httpd.conf impact the behavior of superglobal variables like $_GET in PHP applications, and what steps can be taken to ensure consistent functionality?

The configuration settings in php.ini and httpd.conf can impact the behavior of superglobal variables like $_GET by limiting the maximum size of data that can be passed through GET requests. To ensure consistent functionality, it's important to adjust the settings related to variables like max_input_vars and post_max_size in php.ini to accommodate the expected data size.

// Adjusting php.ini settings to ensure consistent functionality of $_GET variables
// Set max_input_vars to a higher value to allow for larger amounts of data to be passed through GET requests
ini_set('max_input_vars', 1000); // Increase the value as needed
