I still find that printing out variable values at problem points in the code is one of the easiest ways for me to debug.  If you're interested in knowing the full contents of an object/array/scalar, then use 



var_dump($var).

Another free (GPL) debugger is Gubed, http://gubed.sf.net .

Currently available for Linux, but also Windows soon.

Tired of manualy printing out your variables and arrays for debugging?



Take a look at my debuglib at:

Happy debugging!

I've tried many debuggers and PHP IDEs including Zend IDE, Komodo, PHPEdit, PHPEd and Maguma Studio.

 After all I'm sure that the best one debugger is dbg. It supports breakpoints even conditional ones,  all kind of steps throu php code, watch etc, so it's a fully functional debugger indeed and profiler too. Fortunately, it's an open-source product as PHP itself. Unfortunately, it does not contain any front-end, but 3rd party PHP IDEs. Seems, as for an IDE the best one is PHPEd 3.1 (http://www.phped.com), former PHP IDE from Ergin Soysal. 

I was also deeply impressed with IonCube accelerator performance (http://www.ioncube.com). Commercial version of IONCUBE is many times faster than the commercial one from Zend (www.zend.com). Huh ?

Hope this info would help someone to find the better way faster.

check out this great, cross-platform, my favourite php debugger:

 http://www.activestate.com/Products/Komodo/



it not only allows "debugging PHP programs locally or remotely, including debugging in CGI or other Web Server API environments", but, besides, is a full fledged Perl, PHP, Python, Tcl, and XSLT IDE. based on mozilla.



current version 1.2.9 costs some money ($29.50 non commercial), previous version 1.1 is free (non commercial).

Both php3 and php4 ( dbg extention ) are supported by Quanta Plus ( http://quanta.sourceforge.net )<br>


It's a full featured IDE for Unix ( KDE )


which supprt PHP too.

There is actually a symbolic debugger for php4 : BIKE.





It only works on unix/linux, and is a bit limited, but it's better than the existing (rather limited) system and typing tons of echos.





See it at :

want a simple way to get errors from php?





from the command line simply type:





"/path-to-php/php.exe your-php-file.php3"





and It'll throw back useful errors





use -q option before the filename to Suppress HTTP Header output.

[Ed: Note: Python loop control is managed through indentation, so you will need to reindent this errata note]


python remote debug listener...





#!/usr/bin/python


#Used for remote debugging of PHP programs.


from socket import *;





#connect and bind to the port


s = socket(AF_INET, SOCK_STREAM);


s.bind("",7869);


s.listen(5);





#little info to print out


print "PHP Remote Debug Application";





#let us try this thing...


try:


    while 1:


        client, addr = s.accept();


        tmp = client.recv(1024);


        while tmp:


            print tmp, "\n";


            tmp = client.recv(1024);


        client.close();


except:


    s.close();


    print "Exit";

I'm copying this note from a post I found on Geocrawler.  I think Thierry diserves a round of applause for actually posting something useful, so...





HooRah!!!!





I'm going to add some syntax highlighting to the code to make it cute, and then we'll see.
