recursion - PHP convert Array to String (Folder & recursive) -


i stuck,....

i have array this:

$myarray['red'][0] = "valuered0"; $myarray['red'][1] = "valuered1"; $myarray['blue'][0] = "valueblue0"; $myarray['blue'][1] = "valueblue1"; $myarray['green'][0] = "valuegreen0"; $myarray['green'][1] = "valuegreen1"; $myarray['green'][top][0] = "valuegreentop0"; $myarray['green'][top][1] = "valuegreentop1"; $myarray['green'][bottom][0] = "valuegreenbottom0"; $myarray['green'][bottom][1] = "valuegreenbottom1";

as output need:

array( 'red/valuered0', 'red/valuered1', 'blue/valueblue0', 'blue/valueblue1', 'green/valuegreen0', 'green/valuegreen1', 'green/top/valuegreentop0', 'green/top/valuegreentop1', 'green/bottom/valuegreenbottom0', 'green/bottom/valuegreenbuttom1' )

so means: if key string, has folder. if key integer value has ne new value.

it's important recursive interprate different sized arrays.

anybody can me this, can't solve recursive thing.... ?

here example of how done

<?php $myarray['red'][0] = "valuered0"; $myarray['red'][1] = "valuered1"; $myarray['blue'][0] = "valueblue0"; $myarray['blue'][1] = "valueblue1"; $myarray['green'][0] = "valuegreen0"; $myarray['green'][1] = "valuegreen1"; $myarray['green']['top'][0] = "valuegreentop0"; $myarray['green']['top'][1] = "valuegreentop1"; $myarray['green']['bottom'][0] = "valuegreenbottom0"; $myarray['green']['bottom'][1] = "valuegreenbottom1";  print_r(flatten($myarray));  function flatten($data,$keys=array()){         $out=array();         foreach($data $key=>$val){                 if(!is_array($val)){                         $out[] = implode("/",$keys)."/".$val;                 }else{                         $out = array_merge($out,flatten($val,array_merge($keys,array($key))));                 }         }         return $out; }

output:

array (     [0] => red/valuered0     [1] => red/valuered1     [2] => blue/valueblue0     [3] => blue/valueblue1     [4] => green/valuegreen0     [5] => green/valuegreen1     [6] => green/top/valuegreentop0     [7] => green/top/valuegreentop1     [8] => green/bottom/valuegreenbottom0     [9] => green/bottom/valuegreenbottom1 )

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
