Frustration getting Xdebug and PHPStorm 3.0 to talk to each other :(

Hi Joe,

xdebug.remote_host has to be IP of the machine where PhpStorm is running (desktop PC) -- it's xdebug who initiates connection, not other way around.

1. Maybe you providing wrong IP address (quite common mistake) ?
2. Please check your desktop firewall configuration (as PhpStorm is the one that will be receiving xdebug connection)
3. Please check if you are able to connect from your Linux box to your desktop (Activate "Run | Start Listen PHP Debug Connections"; go to linux box and try to connect to PhpStorm with help of telnet).
   
4. Make sure that xdebug port number in PhpStorm (File | Settings | PHP | Debug) is the same as in xdebug config (9000) as well as "Can accept external connections" is checked.

You can try setting xdebug.remote_connect_back = On .. so there will be no need to provide specific IP address as xdebug will connect back to calling IP -- more about this (pros & cons) here: http://xdebug.org/docs/all_settings#remote_connect_back

Another possible thing -- path mappings (File | Settings | PHP | Servers -> Use path mappings).

If none of the above helps, please provide debugger logs (ideally both):

• PhpStorm: http://devnet.jetbrains.net/docs/DOC-1202
  
• xdebug: http://xdebug.org/docs/remote#remote_log

Hi Andriy,

Thank you very much for the information.

xdebug.remote_host has to be IP of the machine where PhpStorm is running (desktop PC) -- it's xdebug who initiates connection, not other way around.

1. Maybe you providing wrong IP address (quite common mistake) ?

I have now modified the setting of  xdebug.remote_host to show the public IP address of my broadband connection.

2. Please check your desktop firewall configuration (as PhpStorm is the one that will be receiving xdebug connection)

I have disabled the Windows Firewall, and ensured that port 9000 allows traffic in/out on the Linux server firewall.

But I have a question about how the incoming Xdebug connection finds its way to my particular PC. There are 3 or 4 different PCs connected to the network (mix of wired/wifi) - but of course, they all share the same public IP address.

How does the Xdebug connection find it's way to my PC, and not any of the others on the same network?

3. Please check if you are able to connect from your Linux box to your desktop (Activate "Run | Start Listen PHP Debug Connections"; go to linux box and try to connect to PhpStorm with help of telnet).

I attempted connecting from the Linux server back to my PC using Telnet (having disabled the Windows Firewall), without success - but it brings me back to the same question ... how does telnet connect to my particular PC on the network, and not any of the others?

4. Make sure that xdebug port number in PhpStorm (File | Settings | PHP | Debug) is the same as in xdebug config (9000) as well as "Can accept external connections" is checked.

Settings in PHPStorm are as you specify.

You can try setting xdebug.remote_connect_back = On .. so there will be no need to provide specific IP address as xdebug will connect back to calling IP -- more about this (pros & cons) here: http://xdebug.org/docs/all_settings#remote_connect_back

I tried this, and got the same behaviour as previously, i.e. the page took around 3 minutes to return, which it did with a XDEBUG_SESSION cookie. But no activity from PHPStorm.

Another possible thing -- path mappings (File | Settings | PHP | Servers -> Use path mappings).

I currently don't have any servers defined in this section.  So, I added a new server as follows:

Name: www.mysite.com
Host: www.mysite.com
Port: 9000
Debugger: Xdebug
Use path mappings: checked
(I haven't specified any absolute paths on the server)

After making these changes, I cleared cookies, and retried. Same result (page returned after just more than 3 minutes), but nothing from PHPStorm.

If none of the above helps, please provide debugger logs (ideally both):

• PhpStorm: http://devnet.jetbrains.net/docs/DOC-1202
  
• xdebug: http://xdebug.org/docs/remote#remote_log

I added the following setting to php.ini to generate the log file.

I tried the sequence again, but no log file is being created.

For PHPStorm, I added the following into the log.xml file, as per the instructions:




<category name="#com.jetbrains.php.debug">
  <priority value="DEBUG"/>
</category>

I restarted PHPStorm, and repeated the process.


Same result - page returned in just over 3 minutes with cookie.

The output from the PHPStorm log file from the point of the restart is below:

Hi Joe,

But I have a question about how the incoming Xdebug connection finds its way to my particular PC. There are 3 or 4 different PCs connected to the network (mix of wired/wifi) - but of course, they all share the same public IP address.

How does the Xdebug connection find it's way to my PC, and not any of the others on the same network?

That's what you have to sort out -- you need to use port forwarding (or whatever it may called on your router) to always direct incomming traffic on that particular port (TCP 9000) to a specific IP address inside your home network (in particular, to your desktop PC).

Here is the site that can help you with detailed instructions on how to do it for your particular router: http://portforward.com/english/routers/port_forwarding/routerindex.htm

Ah... (the penny drops...).  I've learned something today... :) - Thank you :)

I've set up the port forwarding, and now PHPStorm is RESPONDING ! woohoo!!

It presented me with a dialog box giving me the chance to accept/refuse the incoming xdebug connection.

I accepted... but now it doesn't appear to be stopping at the breakpoints I have set up.

Is there something else that I need to set up?

(Thanks for your help so far!) :)

Hi Joe,

Because you are doing it for first time in PhpStorm:

• remove any path mappings (delete the Settings | PHP | Servers) -- PhpStorm will ask you again to set them up during debug (that's in case you have not set them up correctly already)
  
• Settings | PHP | Debug --> Xdebug | Break at first line (for external connections) is checked (just in case)

Also -- there are some breakpoints that xdebug is unable to stop at (e.g. multiline array declaration, multiline php statement/function call). Therefore I recommend to start with very simple PHP page, something like that (maybe even on brand new empty project -- just for a first time untill it all sorted):

<?php
$a = 12;
$b = 5;
$x = $a + $b;
echo $x;

Once this is working you can start debugging your real pages.

That's fantastic, Andriy... :)

The breakpoints are working a treat for the simple php code sample.   But for some reason, breakpoints within my Symfony code are not triggering -- I'm not sure why -- but I can investigate that further once I've had some sleep...

THANK YOU THANK YOU THANK YOU for your help!  I *really* appreciate it. :)

Quite likely incomplete/incorrect path mappings.

That's exactly what it was.

Thanks again :)

Andriy,

Thanks for assistance!:)
