i'm beginner in php , mysql, want know how can put values got select query variables. for example used mysql query : $req="select type, titre, auteur, abstract, keywords manusrit file='$name';"; $req1=mysql_query($req); i want put value of column type in $type variable , value of auteur in variable called $auteur , same abstract, , keywords. how can this? first of use pdo instead of mysqli . example : $link = mysql_pconnect($hostname, $username, $password) or die('could not connect'); //echo 'connected successfully'; mysql_select_db($dbname, $link); $name = $_post['name']; $query ="select type, titre, auteur, abstract, keywords manusrit file='$name';"; mysql_query("set names 'utf8'", $link); $result = mysql_query($query, $link); //now fetch result , read 1 one while ($row = mysql_fetch_assoc($result)) { //access colmn print $row[...

is possible display tostring() result in value column in eclipse debugger? by default displays values built-in types , type name + id user types: note, debugger can display tostring() , in separate section (below), not in value column. it possible, if bit clumsy. 1 picture, more thousand words: in preferences, search "detail formatters". optionally define simple return command each type want inspect (if want choose details yourself). then down below, select "show variable details > label variables" (if tostring() enough you) , or "> label variables detail formatters" if want use custom formatters. former makes "type + id" display vanish, tho. simple formatter "not tostring()":

i want calculate function p of x,y: p(x,y) defined integral of function of x , y: p(x,y) = integral(indefinite) of v(x,y) dx now, if have matrix expressing p on uniform grid x , y , how construct function p (which should matrix). obviously if integrated using trapz , obtain vector: x=linspace(-1,1,10); v=magic(10); p=trapz(x,v); size(p) gives 1 10 , not 10 10. assuming that the formula p defined like: p ( x , y ) = integral[ x 0 .. x ] v ( ξ , y ) d ξ ; the integration grid x × y uniform, norm dx × dy ; the rows of matrix v have x constant, first row corresponding the smallest x ; then integral is: p = cumtrapz(v) * dx;

(echo true) else echo false and advise see explanation of if. because answer exists in there.
