As Firebug seems not to be supported in Firefox 50+, can someone please suggest a library other than FirePHP to use for debugging php variables in the web console?

I just need to log variables to the console. In PHP. Those are my only requirements. No "fancy stuff" like breakpoints, watchers etc. needed.

  • Not sure I understand. I think my question is very specific - I need to be able to debug php variables in a web console. That means that the library prints the contents of a variable to the browser and it is viewable in the console just like console.log() in javascript. I realize some people may not understand that but I don't think it's my job to explain what vocabulary means - if someone doesn't understand what it means to debug variables in a web console then they surely won't be able to make any suggestions for software that does so.

  • Do you need breakpoints? Step-by-step processing? Setting "watches"? Marking which variables should be observed? Which part of code maybe is never touched, or is frequently touched? Anything else?

  • No, I just need to log variables to the console. In PHP. Those are my only requirements. PHP. Log variables to console. They are both stated in my question. Commented Dec 21, 2016 at 1:27

Firefox 50+ has a default ChromeLogger: https://developer.mozilla.org/docs/Tools/Migrating_from_Firebug#Server_logs

and not supporting firePHP at this moment https://bugzilla.mozilla.org/show_bug.cgi?id=1335681 hope that the Mozilla will add firePHP to the Console, many functions in my projects using that, I must use Chrome at this time for debugging.

  • 7 months later.. finally made the switch to ChromePHP / ChromeLogger in Firefox. Must say Firefox performance is much better without Firebug / FirePHP. Commented Jul 5, 2017 at 17:34
