PHPstorm cannot call xdebug. how can this problem be solved?

Why does the 'xdebug' extension & nbsp; is & nbsp; not & nbsp; installed error always occur after PHPstorm is installed ?? The wamp & nbsp; server is used. PHP. ini configuration zend _ PHPstorm cannot be called xdebug
After PHPSTORM is installed, why does the 'xdebug' extension is not installed error always occur during program debugging ??
The wamp server is used. The configuration of PHP. ini is as follows:
Zend_extension = "D:/wamp/bin/php/php5.3.10/zend_ext/php_xdebug.dll"

[Xdebug]
Xdebug. remote_enable = on
Xdebug. remote_handler = dbgp
Xdebug. remote_host = localhost
Xdebug. remote_port = 9000
Xdebug. profiler_output_dir = "D:/wamp/tmp"
Xdebug. trace_output_dir = "D:/wamp/tmp"


When I print phpinfo, the xdebug configuration is displayed, but no matter how I call phpstrom or not installed

I have already called configure setting many times, but I still cannot. The port number is also correct.
I downloaded the software from the official website. should there be no bugs?

------ Solution --------------------
I haven't found anything you said for the moment... linux win is normal. generally, no special setup software is needed but php is called. as long as php is normal, phpstorm should be normal.
