What are the potential server settings that may affect the behavior of $_GET in PHP?

The potential server settings that may affect the behavior of $_GET in PHP include variables such as max_input_vars, max_input_nesting_level, and variables_order. To ensure that $_GET works as expected, you may need to adjust these settings in your php.ini file to allow for the proper handling of GET parameters.

// Adjust server settings in php.ini to allow for proper handling of GET parameters
ini_set('max_input_vars', 1000);
ini_set('max_input_nesting_level', 64);
ini_set('variables_order', 'EGPCS');
