What potential pitfalls should be considered when using debug_backtrace in PHP?

When using debug_backtrace in PHP, it's important to be cautious about potential performance issues, as generating a backtrace can be resource-intensive. Additionally, sensitive information such as file paths and function names may be exposed, so be mindful of what data is being output. Finally, be aware that using debug_backtrace in production code can potentially lead to security vulnerabilities if not properly sanitized. 

// Example of using debug_backtrace with caution
$backtrace = debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);
foreach ($backtrace as $trace) {
    // Only output necessary information
    echo "File: " . $trace['file'] . ", Line: " . $trace['line'] . "\n";
}
