Why does xdebug not establish connection with NetBeans?

Question

I try using xdebug with NetBeans to debug PHP. I start debug, and NetBeans waits for ever for a connection with xdebug. I have NetBeans 6.8 (latest version) with the latest MAMP package installed on my mac.

My php.ini looks like this:

[xdebug]
;zend_extension="/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so"
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=localhost
xdebug.remote_port=9000

Answer 1

If your php.ini really looks like what you posted, you have to un-comment the zend_extension line (i.e. remove the ';' at its begninning), so Xdebug is actually loaded.

Then, make sure Xdebug is loaded, calling phpinfo() from a PHP file (just to be sure).

After that : I suppose there should be some options to configure the debugger in netbeans ? If so, is netbeans listening on port 9000 ? (The one you configured in php.ini)

Answer 2

Finally, I had to add the idekey value like this:

xdebug.idekey="netbeans-xdebug"

now it works :-)

Answer 3

The following settings worked for me with NetBeans 7.2 on Mountain Lion after restarting Apache:

zend_extension = /usr/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so
xdebug.remote_autostart=on 
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_mode=req
xdebug.idekey="netbeans-xdebug" 

Answer 4

Mac/MAMP users: If you have tried all of the above and it still doesn't work, reboot your Mac. Restarting the servers through MAMP is not enough.

Answer 5

I used the following with XAMPP 1.8.2 and NetBeans 7.4 with success.

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
xdebug.idekey="netbeans-xdebug"
xdebug.profiler_append = 0
xdebug.profiler_enable = 1
xdebug.profiler_enable_trigger = 0
xdebug.profiler_output_dir = "C:\xampp\tmp"
xdebug.profiler_output_name = "cachegrind.out.%t-%s"
xdebug.remote_enable = on
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_mode=req
xdebug.remote_host = "localhost"
xdebug.trace_output_dir = "C:\xampp\tmp"

Answer 6

for me worked this way (thank you guys +1) /o/

<pre>
zend_extension = "c:\xampp\php\ext\php_xdebug2.dll"
xdebug.remote_autostart=on
xdebug.remote_enable=on
xdebug.remote_enable=1
xdebug.remote_handler"dbgp"
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_mode=req
xdebug.idekey="netbeans-xdebug"
</pre>

Config:
netbeans 7.3 - php 5.4 - xdebug 2.2 - xampp - win7(32bits)

Answer 7

I've read that xdebug doesn't work with the version of PHP what ships with OS X. I got it to work by updating php from version 5.4 to 5.5, using a handy package from php-osx.liip.ch, including precompiled xdebug extension. Use this command:

curl -s http://php-osx.liip.ch/install.sh | bash -s 5.5

Note that this will leave your default php installation intact, but disable it in httpd.conf. Your new php.ini will be at "/usr/local/php5/lib/php.ini", with the xdebug config file at "/usr/local/php5/php.d/50-extension-xdebug.ini".

Setup: OS X version 10.9.2
