FirePHP offers not only ability to monitor errors in log, but also displays other information as a script progresses and dumps value of an array when desired. In addition you can turn on/off all its reporting at with one statement at beginning of code.
Quite handy for use in PHP development - or in understanding code you inherit from someone else. Works for me!
I find it a very useful development aid. I'm just hoping more browsers (well, my preferred browser) start having something that can interpret the FirePHP stuff :-)
Bad submission title (I know it's same as the title of the page, but they're both bad). Outputting log statements is not debugging. Well, perhaps for PHP programmers it is due to the pathetic state of debuggers for PHP, but for anyone using a decent language it isn't.
