In what ways can server configurations impact the security of a PHP application, and how can these configurations be optimized to mitigate risks?

Server configurations can impact the security of a PHP application by exposing sensitive information, enabling insecure features, or allowing malicious code execution. To optimize server configurations and mitigate risks, ensure that error reporting is set to not display errors to users, disable dangerous PHP functions like eval() and system(), and configure secure file permissions to prevent unauthorized access. 

// Disable error reporting for displaying errors to users
ini_set('display_errors', 0);
ini_set('display_startup_errors', 0);

// Disable dangerous PHP functions
disable_functions = eval, system;

// Set secure file permissions
chmod('/path/to/file', 0644);
