How can PHP developers troubleshoot issues with error reporting and exception handling on different server environments?

PHP developers can troubleshoot issues with error reporting and exception handling on different server environments by checking the PHP configuration settings for error_reporting and display_errors, ensuring that error reporting is set to E_ALL and display_errors is set to On. Additionally, developers can use try-catch blocks to handle exceptions and log errors to a file for further investigation. 

// Set error reporting level and display errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Set custom error handler to log errors
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    error_log("Error: [$errno] $errstr in $errfile on line $errline");
}
set_error_handler("customErrorHandler");

// Example try-catch block for exception handling
try {
    // Code that may throw an exception
    throw new Exception('An error occurred');
} catch (Exception $e) {
    error_log('Caught exception: ' . $e->getMessage());
}
