php - How to retrieve data from MySQL database and save it to xml file -


need im badly stuck here. have mysql database , html form.i can connect database through form without problem. buttons (find, delete, update , add) work perfectly.now decided add print button suppose export retrieved data xml file(that converted pdf file later know how deal that). idea how or start??? there php function can use?

i resolved issue creating function print button , calling function later. working perfectly. 

 function printrecords($query){  global $id, $name, $address,$country, $ph_number;  $result = mysql_query($query);  $resultcount = mysql_num_rows($result);     $query= 'select id, name, address , country, ph_number people';     $fp= @fopen ("somefile.xml","w")or          die ("could not open file");      $data = "";     ($r=0; $r<$resultcount; $r++) {          $rec = mysql_fetch_assoc($result);         $data = sprintf("<name>%s</name>\r\n<address>%s</address>\r\n         <ph_number>%s</ph_number>\r\n"         $rec['name'], $rec['address'], $rec['ph_number'] );          fwrite($fp, $data);     }     @fclose($fp);     return($resultcount);  }

tried xml export via mysql command line ?

e.g.

mysql -uroot -p --xml -e 'select * mydb.table1' > table1.xml

see mysql manual command options xml

and saw have access database thru html form, , maybe can't run command line?

otherwise own xmldoc select, simple query made here sqlfiddle.

create table animal(id int, name char(10));  insert animal values (1,'dog'), (2,'cat'), (3,'mouse'), (4,'horse'), (5,'cow');  select    concat('\n<animals>\n',    group_concat('<animal id=', id, '>',name,'</animal>\n' separator ''),    '</animals>') xmldoc  animal;

output be:

<animals>    <animal id=1>dog</animal>    <animal id=2>cat</animal>    <animal id=3>mouse</animal>    <animal id=4>horse</animal>    <animal id=5>cow</animal>  </animals>

the sqlfiddle

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
