It's actually a combination of php and bash:
exec(sprintf("%s > %s 2>&1 & echo $! >> %s", $cmd, $outputfile, $pidfile));
I don't understand what 2>&1 & echo $! is there for?
For linux driver development, I can refer to <linux driver development>
What about windows driver development?
UPDATE
Is there any goold books on this topic?
I'm using pdo to do this :
update tags set cnt=cnt-1 where name in ?
delete from news_tag where news_id=? and tag_id in (select id from tags where name in ?)
But if I can get affected rows' id,the subquery is not needed.
I wander how do client side get response if the connection of request is not finished yet?
What's the principle?
In fact I've read quite a few posts on this subject:

But none of them solve my doubt
bwlabel can be used to get disconnected objects in an image:
[L Ne] = bwlabel(image);
I want to make the objects(But my target is only the contours of these objects) connected by adding a shortest path where necessary.
How do I approach this?
Somehow I don't like IDE very much,
but I don't find a particular good tool to build java applications from source yet.
I welcome all kinds of feedbacks!
Quoted from here:
BW = edge(I,'zerocross',thresh,h)
specifies the zero-cross method, using
the filter h. thresh is the
sensitivity threshold; if the argument
is empty ([]), edge chooses the
sensitivity threshold automatically.
If you specify a threshold of 0, the output image has closed contours,
because it includes all the zero
crossings in the input image.
I don't understand it,can someone elaborate?
bwlabel can be used to get disconnected objects in an image:

How to calculate the shortest path between two disconnected closed curves?
Is there a practical(not theoretical) solution?
I'm having a hard time installing zend_debugger, somehow the installed version doesn't match with my php.
Is there a repository for all versions of zend_debugger?
test.c:
include "file.h";
In the above statement, which directories will be searched ?
I suppose the directory where test.c locates will be searched, right?
But is that all?
BTW, what's the benifit to use a header file? Java doesn't require a header file...
Notice: Constant DIR_FS_CATALOG already defined
I've already commented out display_errors in php.ini,but is not working.
How do I make PHP not output such things to browsers?
I've noticed that the Title or Body part is remembered if I come back to the Ask Question page by pressing Back button of my browser.
How can I approach that effect?
