Xdebug - command is not available

Question

I'm debugging remotely my project in PhpStorm. IDE shows 'Connected' for a moment and immediately goes into 'Waiting for incoming connection...'

Below is Xdebug log from this session

I: Connecting to configured address/port: X.x.x.x:9000.
I: Connected to client. :-)

According to Xdebug documentation status "stopping" is 'State after completion of code execution. This typically happens at the end of code execution, allowing the IDE to further interact with the debugger engine (for example, to collect performance data, or use other extended commands).'

So my debugger stops before reaching first breakpoint (set on first line).

Could it be a question of server configuration?

You should go to php.ini and delete a line like this

extension=php_xdebug-...

---

How did this line was created.

You put a xdebug's file into PHP extensions path like this

.../php5.X.XX/ext/

Now you may turn on this PHP extension by any _AMP UI tools like WAMP, XAMPP etc.

---

To prevent this painful misfortune you must put the Xdebug file into

.../php5.X.XX/zend_ext/

It'll make Xdebug hidden from any _AMP tool.

And correct your zend_extension parameter too.

zend_extension = .../php5.X.XX/ext/php_xdebug-...

to

zend_extension = .../php5.X.XX/zend_ext/php_xdebug-...

It's common default path for it.

Please, remember!
With PHPStorm, Eclipse, Zend etc., possibly you should consider to correct two php.ini files.

The first one for your web server. Commonly under Apache folder

...\Apache2.X.XX\bin\

The second one is for the direct PHP-script debugging. It lies in the PHP hosting folder:

...\php\php5.X.XX\
