How can PHP developers prevent error messages from being displayed in the browser window while still logging them for debugging purposes?

To prevent error messages from being displayed in the browser window while still logging them for debugging purposes, PHP developers can use the ini_set function to set the display_errors directive to off and the error_log directive to a specific file path where the error logs will be stored. 

// Turn off error display in the browser window
ini_set('display_errors', 0);

// Set the error log file path
ini_set('error_log', '/path/to/error.log');

// Trigger a sample error for testing
echo $undefinedVariable;
