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'm using jssor slider display product images on 1 of sites. i'm using slider thumbnail navigation , products standard implementation works standard. however, there number of products various options chosen drop-down list (each of has it's own specific image). load thumbnails loop through database table , same populate drop-down list. what selection of specific drop-down option trigger same action clicking on relevant thumbnail , load full size image. before added jssor slider product page had used javascript selected index , change main image source way: http://www.scotcrest.com/singleproduct.php?action=more+details&productid=18&productname=clan%20cloot%20tea%20towels (that's current version - without jssor) but i'm not experienced jquery (i'm working php) i'm @ loss how work in jssor functions. i've tried looking @ code triggered on clicking on thumbnail , trying fire on changing select box didn't anywhere. this new versio

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.

i've not been able find conclusive answer far. when safe call this-> within object. , in particular inside constructor , destructor. and also, when using public inheritance. safe use , downcasting on result of call? so example: class foo { foo(): a(), b(this->a)//case 1 { this-> = 5; //case 2 } int a; int b; }; class bar: public baz { bar(): baz(this)//case 3 - assuming baz has valid constructor { } } and unlikely one foo() { if(static_cast<bar*>(this));//case 4 } which of above cases legal? note: i'm aware lot of practices above inadvisable. within non-static member function, this points object function called on. it's safe use long that's valid object. within body of constructor or destructor, there valid object of class being constructed. however, if base sub-object of derived class, base sub-object valid @ time; it's not safe down-cast , try access members of
