What potential pitfalls should be considered when logging PHP errors to a file?

One potential pitfall to consider when logging PHP errors to a file is the risk of exposing sensitive information, such as database credentials or user data, in the error log. To mitigate this risk, ensure that only essential error information is logged and avoid including any sensitive data. Additionally, make sure that the error log file is stored in a secure location with restricted access to prevent unauthorized users from viewing its contents. 

// Set the error log file path
$logFile = '/path/to/error.log';

// Log only essential error information
ini_set('error_log', $logFile);

// Ensure that the error log file has restricted access
chmod($logFile, 0600);
