Xdebug stopped working, where do I look for errors?

Question

I installed Xdebug and all was fine, until suddenly it stopped working. phpinfo() gives a nice XDebug output with all variables.

php -m | grep deb 

also gives twice XDebug (for Zend and PHP), so again looks just fine. My php.ini has these lines:

zend_extension=/usr/lib/php5/20090626/xdebug.so ;extension=xdebug.so xdebug.remote_host=localhost xdebug.remote_enable=on xdebug.remote_port=9001 xdebug.remote_handler=dbgp xdebug.remote_connect_back=1 

And yet, when running this code with should check XDebug (from Netbeans docs) it's just stuck. So No IDE is working with XDebug.

<?php $address = '127.0.0.1'; $port = 9001; $sock = socket_create(AF_INET, SOCK_STREAM, 0); socket_bind($sock, $address, $port) or die('Unable to bind'); socket_listen($sock); $client = socket_accept($sock); echo "connection established: $client"; socket_close($client); socket_close($sock); 

Also, according to XDebug installation, I went twice throught the steps. What is wrong with my config? Thanks.

Answer 1

At the end, left with only two solutions - to reinstall the Ubuntu OS or to install a new VM especially for xdebug, I'm going for the second one. Funny thing is, everything was working according to the "RTM" (f=freaking). One thing that I couldn't figure out is how to read the logs for XDebug in order to understand where the real problem is.

UPDATE

After some struggling, I deleted every single line related to xdebug from every php.ini that I had. And moved these lines to /etc/php5/conf.d/xdebug.ini. Restarted Apache, and then PHPStorm, and it works. P.S. in the middle, I tried to install xdebug with pecl, from github, and the standard Ubuntu version. I think the one that I compiled is currently working. And.. the log gets updated as well.

;xdebug configuration zend_extension = /usr/lib/php5/20090626/xdebug.so xdebug.remote_host = 127.0.0.1 xdebug.remote_enable = 1 xdebug.remote_port = 9000 xdebug.remote_handler = dbgp xdebug.remote_mode = req xdebug.profiler_enable=0 xdebug.profiler_enable_trigger=1 xdebug.remote_autostart=1 xdebug.idekey=PHPSTORM xdebug.remote_log="/tmp/xdebug.log"

On your server, try this command:

$ netstat -anp | grep CLOSE_WAIT

Any :9000 entries will give you XDebug troubles; consider kill -9 <pid>.
