NetBeans + XDebug Breakpoints not working - php

I know there are countless of questions regarding this subject, however no matter what I've tried I've had no luck whatsoever. The problem I'm encountering is regarding breakpoints when using NetBeans and XDebug (on Windows 8.1 if that affects anything).
The issue is that no breakpoints are working. By default when debugging with NetBeans, it stops on the first line and this does successfully happen. Therefore NetBeans is somehow connecting to XDebug. However, any other breakpoints in any other files are not working.
I've tried various different settings in the php.ini file but no luck so far. I've also tried switching on the XDebug log file so that maybe I can analyse what's going on, but this also didn't work. Finally I've tried setting breakpoints using xdebug_break() which also didn't work.
XDebug settings in php.ini

Project Run Configuration on NetBeans
I've already looked at the following:
http://articlebin.michaelmilette.com/making-xdebug-work-with-netbeans-on-windows/
Xdebug ignores breakpoints
http://wiki.netbeans.org/HowToConfigureXDebug#Tips_from_the_NetBeans_Forums
Also note that this was working 3 days ago, however today no breakpoints are working.
Additional Info
I've run the following command in cmd php -v and the following warning was shown:
Warning: Module 'xdebug' already loaded in Unknown on line 0
Does this mean that xdebug is trying to be loaded twice? If so I'm not sure how this can be solved

Figured out what the problem was. I know that this answer will be very specific, however it might help someone in the future.
So while inspecting the code I noticed that someone added code that cleared all cookies when the login page loaded. Once the cookies are removed XDebug didn't work. The reason is that for XDebug to work it sets a cookie with the session id for example 'netbeans-xdebug' which is sent with every request on the website.
It's a very simple issue but it took nearly 2 days to find out what was going on. Once again I know that this is a very specific case but maybe it might help someone out there.
Happy coding!

Xdebug not stepping over or into - using VSCode and Windows

Hopefully the following will give you enough to go on.
My setup
I'm using:
Windows 10 (now at build 19043.1288),
VSCode (v1.61.2) with
PHP debug (v1.21.1),
both Firefox and Google Chrome browsers,
XAMPP (v3.3.0)
Xdebug (now v3.1.1-7.4x86_64)
I'm also running Ubiquiti network controller, and BitDefender AV in the background.
PHP.ini
[Xdebug]
zend_extension = xdebug
;zend_extension = "c:\xampp\php\ext\php_xdebug-3.1.1-7.4-vc15-x86_64.dll"
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_port = 9000
xdebug.log = "c:\xampp\htdocs\j4\tmp\xdebug.log"
Problem
I've had VSCode/XAMPP/Xdebug working with Joomla 3 for well over a year without issues. I went away for a couple of weeks and when I came back I wasn't able to single step into any of the Joomla 3 modules/classes. VSCode would stop at breakpoint, but both single step and step into immediately went to the parent calling function.
Ah, I said to myself, probably Windows did something - may be a good time to upgrade to J4, as well as update my environment. Same problem. Stops at 1st breakpoint, won't single step or step into - it won't stop at subsequent breakpoints. Appears to single step in the core J4 modules. Stack appears normal - initialised variables can be inspected.
What I've tried
Everything! To keep this relevant - I've now installed a completely fresh, out of the box, unadulterated, XAMPP, Joomla4 and Xdebug (as recommended by Xdebug wizard). I've also temporarily disabled my AV (BitDefender). I don't have any firewalls on my PC, as I'm behind a network firewall.
Just in case, I did a deep virus scan and disk check - nothing.
Prior to installing everything fresh, I was able to get an Xdebug log file, but now I can't. I also noted that the breakpoints wouldn't reset - I'd remove all the BPs and they'd come back on next run. I'd have to stop and restart the PHP debug in VSCode to make them go away.
I suspect that the latest Windows updates (or maybe the last few), did something to my dev environment.
However, it's also possible that I've missed something stupid in the setup, as I've been round the circuit several times already, and my head isn't functioning as it should.
Where I need help
I'm now at a loss at what to try next - any suggestions? If no-one else can reproduce this - it means something in my system has glitched, any help would be appreciated.
Update 1
I discovered that a v2 of Xdebug had crept into my php/ext directory - not too sure how - and that was why I wasn't able to get a log file to work. I now have the correct version (3.1.1) of Xdebug installed and working. The single step issue, however, remains.
I now have a log from VSC debug console as well as from xdebug.log: see here
One thing I observe is that there are many errors associated with deprecated functions - I would have expected them to be warnings and not errors!
There are also numerous cases of "error evaluating code".
I have highlighted the place where the code stopped in the logs with "************". I don't know if this is expected or normal, but it does seem to occur a short time before the breakpoint stop - line 431 vs line 651 in the debug console log.
Update 2
Just in case anyone has any interest - I installed the latest version of Eclipse IDE with PDT. Used exactly the same XAMPP/htdocs directory as before - and Xdebug works as expected. No issues with single stepping.
This means, I believe, that Windows, XAMPP, Xdebug and Joomla can be ruled out as culprits, as these are common to both environments. Conversely, it also means that there's something going on with VSCode, or at least with my particular VSCode setup.
Breakthrough (I think!)
It appears that a couple of variables (e.g. $this->missingclasses) I had put into the watch window were causing the problem. I suspect that over the course of a few VSCode updates the persistent internal objects associated with those variables had glitched/corrupted. When I deleted the offending variable watches - single step started to work again.
After seeing that that worked, I was able to put the watches back and single stepping worked as expected. Putting the same watched variables into Eclipse had no effect on single stepping.
Just for good measure, I also deleted and reinstalled PHP Debug - although I'm pretty sure the watched variables, that couldn't be evaluated, were the real issue here.
I will leave this a couple of days, and then I'll close this with a suggested solution

Netbeans start xdebug on specific page

I have been programming PHP for quite some time but have never used an IDE or debugger to assist with this process. I decided to try and learn Netbeans with XDebug for PHP code assistance. Setting things up in the ini files was easy enough and I can verify that it is working. However, when I start the debugger in Netbeans it loads the index page of my site and the page I actually want to debug is 5 pages deep and can take a long time to navigate to with the debugger on.
I have installed the Xdebug helper for Chrome but the debugger gets suspended in Netbeans and never debugs anything on the page. Here are the steps I tried with the Xdebug helper. Note: I already set breakpoints in Netbeans.
Navigate to the page I want to debug.
Turn on Debug in Xdebug helper.
Reload page.
Here is the screenshot showing that the debugger appeared to start but suspended and stopped functioning I think.
So, I am looking for a bit of guidance and support figuring out if I may be using the tool wrong or if there is a better way to use it. Is there a way to activate it for a specific page and keep it running to debug ajax requests to php on the same page/project?

Debugging with eclipse and xdebug won't go past the first line

Yes I have tried searching on StackOverflow and Google for my problem. If you read the entire question you will see that I include a lot of links to previous answers that I found using both.
I have been trying to get XDebug working with Version: Juno Service Release 2 of Eclipse for about the past hour and a half and I'm running into a log of issues. I've already solved most of my problems by using stack overflow and Google.
I followed the steps here first to install the debugger.
I made sure that I added the debugger as a zend_extension as mentioned in this post.
Here are the relevant lines from my php.ini file
zend_extension="/Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so"
xdebug.collect_params=4
xdebug.var_display_max_depth=999
xdebug.dump.POST=*
xdebug.dump.GET=*
xdebug.show_local_vars=1
I made sure that I edited the php.ini file for the 5.3 version of php that comes with MAMP. At this point the debugger would start even though XDebug does show up when I run php -v.
Since I was still having issues I checked the logs just like someone did here. I noticed this error in the logs:
PHP Fatal error: Class 'Model' not found in ...
After checking the documentation for the latest version of CodeIgniter I noticed that all Models have to extend CI_Model and not Model.
I fixed that and the error is no longer being printed to the logs, but now things just don't work. The debugger won't go past the first line when I try to debug a file.
I'm trying to debug my php application as a PHP CLI Application. When I try to debug the application as a PHP Web Application I get an error message that says:
No tab group defined for launch configuration type org.eclipse.php.debug.core.launching.webPageLaunch
After Googling the problem, I came across this post that suggested that you might not be able to do what I'm trying to do. Since the question was first asked in 2009, I decided to try the second suggestion and check for any updates.
After updating all of my Eclipse plugins I was still having the same problem. After searching on SO some more, I saw that this guy just gave up and tried with NetBeans and got everything to work.
Should I just consider the past 1.5 - 2 hours as a sunk cost and just move on to a different IDE?
I also had issues getting XDebug to work with Eclipse and XAMPP. In the end I decided to go with Netbeans and it was a lot smoother getting it setup. I am still using Netbeans to date for all of my PHP development.
Possibility your Php CLI is picking wrong php.ini file ?
Please go to terminal and check which ini file is loaded by :
php --ini
and make sure its desired one.
jerrod.taylor,
I had a lot of issues when starting use PHP,Xdebug and Eclipse. I considered change IDE myself but I liked the challenge and found a lot of help online. I will try to provide you with some tips will help you.
First of all this is the parameters I have in my php.ini:
zend_extension="/usr/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so"
xdebug.remote_enable=On
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9060
xdebug.remote_handler="dbgp"
xdebug.remote_autostart=On
I am using local machine as remote host. Adapt for your world. This configuration works for me with CLI and Web debugging. I am really not sure if some of them is specific for different kinds of debug. So, lets start with all of them.
Now, make sure xdebug is been supported. Run the following command and see if exist something not good.
php -i|grep xdebug
NOw, lets go to Eclipse. In Eclipse preferences add the correspondent PHP executable and make sure the debuger type is Xdebug. This step can be done navigating through Preferences->PHP->PHP Executables. If you add an item, the form you ask you for the following information:
Name : Choose one
Executable Path : the_path_to_php_exe
PHP Ini file : you can leave it blank
SAPI type : CLI
PHP debugger : Xdebug
This step is important. It is how we will tell eclipse the executable to use.
Now, lets add a debug configuration. I have one project called upload in my workspace and exist a file index.php on this project. To create a debug configuration click in new when "PHP CLI Application" is selected. It will be add a new configuration form for you. For my Debug configuration I have the following information:
Tab PHP Script
Run Time PHP
Alternat PHP: (Select the PHP executable you have created above)
PHP File : /upload/index.php
Break Point : Break at first line is selected
This steps should be enough to you solve your issues. Let us know how it was.

Breakpoints not working in Eclipse with XDebug

I have been trying to set up debugging using XDebug in Eclipse for the last few hours without success.
I have the following in my etc/php5/apache2/php.ini file
[XDebug]
xdebug.remote_enable=on
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_autostart=off
zend_extension = /usr/lib/php5/20090626+lfs/xdebug.so
The zend_extensions = /usr/lib...... was given to me by the custom installation instructions on the XDebug site. I followed the setup instructions exactly as they are on that page - http://xdebug.org/wizard.php
But from what I have read typing the command php -m should show XDebug twice, once under PHP modules and once under Zend modules. Well it is showing up under neither for me. So it seems that XDebug is not getting loaded at all?
Anyone any ideas on how to fix this problem and get XDebug working?
You've editted /etc/php5/apache2/php.ini file which is for apache. You'd want to edit /etc/php5/cli/php.ini for the command line interface's options.
If you pass in the phpinfo() from a web site, that PHP has run through Apache of course. And then the wizard will give you settings for the Apache set-up. If you would have passed the phpinfo() output (php -i) from the command line, it would have given you the settings for the CLI.
Something similar happened to me, the first time I setup xdebug in Eclipse it worked just fine, but the next time I tried it, it wasn't stopping at breakpoints. After a lot of research it turned out that I had 2 Eclipse instances running (one for Java and another for Php) and that caused some kind of issues with the debugger.
After closing both instances and starting Eclipse with php workspace first and then Eclipse with java workspace, xdebug worked fine again. My only idea is that debug port was already used when I tried to use it; or something like that.
An other common problem is that you use a router to get through INTERNET and that you had to forward XDEBUG PORT (generaly 9000) on your PC to make XDEBUG working with ECLIPSE.
But your router gives a dynamic IP to your PC and one day your mobile phone connects to the router before your PC and gets the IP address you configuredon you router IP FORWARDING !
The solution getting a static IP from your router. Here is an explanation: http://webologix.com/fr/blog/xdebug-eclipse-fonctionnement-aleatoire.html

PHP: Profiling code and strict environment ~ Improving my coding

I would like to update my local working environment to be stricter in an effort to improve my code. I know that my code is okay, but as with most things there is always room for improvement.
I use XAMPP on my local machine, for simplicities sake Apache Friends XAMPP (Basic Package) version 1.7.2 So I've updated my php.ini : error_reporting to be E_ALL | E_STRICT to help with the code standard. I've also enabled the XDebug extension zend_extension = "C:\xampp\php\ext\php_xdebug.dll" which seems to be working, having tested some broken code and got the nice standard orange error notice.
However, having read this question, Profiling PHP code and enabled the profiler, I cannot seem to create a cachegrind file.
Many of the guides that I've looked at seem to think you need to install XDebug in XAMPP which leads me to think they are out of date, as XDebug is bundled with XAMPP these days.
So I would appreciate it if anyone can help point me in the right direction with both configuring XDebug to output grind files, and or just a great set of default settings for the XDebug config in XAMPP. Seems there is very little documentation to go on.
If people have tips on integrating these tools with Netbeans, that would be awesomesauce.
I'm happy to get suggestions on other things that I can do to help tighten up my php code, both syntactically and performance wise
Thanks, and apologies for the rambling question(s)!
Ninja edit
I should menion that I'm using named vhosts as my Apache configuration, which I think is why running XDebug on port 9000 isn't working for me. I guess I'd need to edit my vhost to include port 9000
If you always want to run the profiler:
xdebug.profiler_enable = 1
else if you want to selectively switch the profiler on (a good thing), use:
xdebug.profiler_enable_trigger = 1
If you're triggering, you'll need to using the XDEBUG_PROFILE GET/POST parameter, or send a cookie with the name XDEBUG_PROFILE. There are browser add-ons to help; For Firefox I use Xdebug Helper, but as it seems to have disappeared you could try easy Xdebug.
I found that the default output dir didn't work, so try setting it yourself:
xdebug.profiler_output_dir = /home/deebster/php/profiler
Remember to set the directory's permissions to allow Apache to create files if you don't use /tmp
