Anhang D. Der PHP-DebuggerVerwendung des Debuggers
Der integrierte Debugger von PHP ist n�tzlich, um schwer zu findende
Fehler aufzusp�ren. Jedesmal, wenn PHP startet,
stellt der Debugger eine Verbindung zu einem TCP-Port
her. Jede Fehlermeldung wird nun an diese TCP-Verbindung ausgegeben.
Damit l�sst sich ein "debugging server" einrichten, der innerhalb
einer IDE oder eines programmierbaren Editors (z. B.
Emacs) l�uft.
Den Debugger einrichten:
Geben Sie in der Konfigurationsdatei
(debugger.port)
einen TCP-Port f�r den Debugger ein und aktivieren Sie ihn (debugger.enabled).
Dann richten Sie einen TCP-Listener ein,
der auf dem Port horcht (zum Beispiel socket -l -s
1400 unter UNIX).
Schreiben Sie in Ihren Code die Anweisung
"debugger_on(host)", wobei
host die IP-Adresse oder der Hostname
ist, wo der TCP-Listener l�uft.
Nun werden alle Warnungen, Hinweise, etc. auf diese Schnittstelle
ausgegeben, sogar wenn sie mit error_reporting
() abgeschaltet wurden..

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.

[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";

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.

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

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

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 (), former PHP IDE from
Ergin Soysal.
I was also deeply impressed with IonCube accelerator
performance ().
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.

Tired of manualy printing out your variables and arrays for
debugging?
Take a look at my debuglib at:
Happy
debugging!
