The following assumes object-oriented programming paradigms are at least
somewhat applied. I would guess functional would be similar, but procedural
code, you might be on your own there...
I actually use two classes that I include at the bottom of all of my library
definitions (in if(!class_exists()){declare}format). One provides warning
and error message storage, the other type assertion. Between the two of
these, I have simple unit testing that I can perform as I am developing a
class, as well as pre-included simple error logging that, when I install
into the greater system, can be incorporated into the systemic error
catching routines without refactoring code, in most cases to weld-on
systemic error routines.
Thinking aloud, getting code to work correctly usually means testing it
against what you expect it to do, so doing that at a very localized level
first can be helpful. Once I started doing this, my implementation issues
somewhat went away. Results (and implementations) may very.
PS Why are we doing this? Because we are getting tired of debugging
with Javascript alert() boxes. /mt
Firebug in Firefox is a very well-developed javascript debugger, featuring
console.log(), which allows you to stop using alert() for error checking.
Very nice! And I put this:
code
// Solve the firebug extension issue in IE by try/catching and creating a
blank object console.log();
try{console.log();}catch(e){var console=new
Object;console={log:function(){var k=0;}};};
/code
At the head of each js file to prevent errors in IE or other browsers
without Firebug installed.

[PHP] Re: PHP debugger
Currently I'm Using PDT/XDebug on daily basis and works just fine. You can get Xdebug from www.xdebug.org, PDT from www.eclipse.org/pdt and the plugin for PDT to add support to the PDT is https://bugs.eclipse.org/bugs/show_bug.cgi?id=169408 In the plugin precompiled package you'll find a pdf with instruction how to get things working. On the Xdebug site there's a lot of information how to setup PHP and XDebug. Note that the precompiled binary of the support for PDT will work for you, as it's written in Java and you don't need to compile it.

Re: [PHP] debugger for CLI PHP scripts...?

Hi Christopher
Spoken as someone who actively uses PHP both in webpages, and for scripts on
CLI, the only debugger I am aware of is Gubed (but that's only for PHP
Webbpages)
Personally, I use the following setup (pseudo code, I could give you the
actuall source code, but this is better because it will actually enhance your
knowledge)
This does not have breakpoints, but if you want them, you can write a function
function breakpoint($info)
{debug($info);
die();}
After that if you want conditional breakpoints, use an assert like function
function assert($var,$value,$msg)
{if($var==$value)
breakpoint($msg);
}
Do you see the light yet?
If you implement it properly, you don't even need to change your source code
when debugging is done.
example flow:
Register_shutdownfunction(debug,dump);
then everywhere in the script,
function dosomething($param)
{debug(domsomething($param));
...
}
function debug()
{static $data='';
get parameter list
if first param=dump
{if preferences=dumtofile
writetofile $data
else
writetoconsole $data
}
else
data[]=$parameters
}
}
Can you see the use of this?
Kind regards
Andy

You know, with single stepping, breakpoints, examining vars, etc. 100% of my PHP stuff is CLI (wacky, huh?) and I'd really benefit from a traditional debugger. Oh btw, I'm looking for a free/opensource one. I suspect the IDEs are tied into the web-server with --enable-debug... You *could* set up your dev box to run your CLI scripts through the web server, just for testing/debugging...

Re: [PHP] debugger
There are some IDE's that support debugging or you can just use the parser. It will tell you the problem and spit out a warning or error depending on how you have your php.ini set up. I usually have display_errors on so that I can use that as my debugger. Then when I go on a live server I have it turned off and I have errors being logged to a file. Debugger for poor developers...

Hi to all!!!
Can anyone tell me how to debug in PHP?
When I use ASP simply I write stop (VB) or debugger (JSCRIPT) to set a
breakpoint and open the Microsoft Script Debugger.
With PHP I can't find a way to do a similar thing.
I downloaded the DBG PHP debugger but I don't understand how to use it like
MSD.
My config is:
PHP 4.1.2 + IIS5 + WinXPpro
I'm bored to use echo $something for debug :-(
Thanks in advance for your help,
Evan
I´m not shure, but ZEND offers some kind of IDE and nusphere has an IDE
which has a debugger built in , but who needs this??
Use an editor with macro functionality so u can set a macro which makes
something like if($debug){ echo something}, then you can set one var
to turn debugging on/off.
Are you shure you need PHP for your problems? Seems that you´re lucky
with M$ and their ek$pen$ive environments.

Re: [PHP] Debugger, Debugger and Debugger
You must be viewing old documentation.
http://php.net/manual/en/debugger.php
clearly states that debugger, ie debugger_on() support is in php3 only, not
in php4.
Your not out of luck though, you could still use the Zend Debugger, the Zend
boys seem to be quite eager to improve its current quallity.

Hi,
Problem:
I'm trying put to work the debugger in php4.0.4pl1(Red Hat Distribution),
I
change my php.ini file to enable the debugger but when try to use in a
simple
script I get the following error:
Fatal error: Call to undefined function: debugger_on() in
/var/www/html/php/dbg.php on line 2
Questions:
1º Do I need some sort of extension (something like xxx.so) to activate
the
debugger?
2º In php documentation (Chapter: Using the Debugger) says:
Set up a TCP listener on that port somewhere (for example
socket -l -s 1400
on UNIX).
I don't have that "socket" command in Linux/Unix, what is this?
What this means?
3º I need to debug my script what is the best way to do that?
(I tried the "Zend IDE Test Drive" but after 30 days is not for free
and
can't put to work the "The DBG PHP Debugger").
4º What is the difference between Zend debugger, Dmitri Dmitrienko PHP
debugger
(seen link below) and the 'internal' PHP debugger?
Thanks, (Sorry for the bad english)
