FirePHP : Firebug Extension for AJAX Development
What is FirePHP ?
FirePHP enables you to log to your Firebug Console using a simple PHP method call.
All data is sent via response headers and will not interfere with the content on your page.
FirePHP is ideally suited for AJAX development where clean JSON and XML responses are required.
WARNING: Using FirePHP on production sites can expose sensitive information. You must protect the security of your application by disabeling FirePHP logging on your live site. You can do this by removing the logging statements before you upload your code or by restricting FirePHP logging to authorized users only.
