php - associative arrays and array_merge -


print_r($element_attrs); returns following arrays gathered xml file.

array ( [weather-summary] => thunderstorms )  array ( [weather-summary] => thunderstorms )  array ( [weather-summary] => chance thunderstorms )  array ( [weather-summary] => cloudy )  array ( [weather-summary] => sunny )  array ( [weather-summary] => clear )  array ( [weather-summary] => sunny )  array ( [weather-summary] => clear )  array ( [weather-summary] => sunny )  array ( [weather-summary] => partly cloudy )  array ( [weather-summary] => sunny )  array ( [weather-summary] => partly cloudy )  array ( [weather-summary] => sunny )  array ( [weather-summary] => rain fog/mist )  array ( )

right 16 separate associative arrays in keys same except last 1 that's blank reason. i'd merge these separate arrays 1 big array using array_merge() or function can return second last value says "rain fog/mist"

right when print_r(array_merge($element_attrs)); get:

array ( [weather-summary] => thunderstorms )  array ( [weather-summary] => thunderstorms )  array ( [weather-summary] => chance thunderstorms )  array ( [weather-summary] => cloudy )  array ( [weather-summary] => sunny )  array ( [weather-summary] => clear )  array ( [weather-summary] => sunny )  array ( [weather-summary] => clear )  array ( [weather-summary] => sunny )  array ( [weather-summary] => partly cloudy )  array ( [weather-summary] => sunny )  array ( [weather-summary] => partly cloudy )  array ( [weather-summary] => sunny )  array ( [weather-summary] => rain fog/mist )  array ( )

assuming have array of of values of $element_attrs arrays should work.

function getlastweathersummary($arr){     $ret = array();     foreach($arr $summary){        if(array_key_exists("weather-summary", $summary)){           $ret[] = $summary["weather-summary"];        }     }     // if want whole array      // return $ret      // if care last 1     return array_pop($ret); }

if care last 1 when assigning each of $element_attrs values can 

// loop through elements , set value of $element_attrs if (array_key_exists("weather-summary", $element_attrs)){     $last_summary = $element_attrs["weather-summary"]; }

after loop should end variable named $last_summary contains last defined value.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
