Android screen height and width

Published by Silveira on 2011-03-12 
Context ctx = getContext();
Display display = ((WindowManager)ctx.getSystemService(ctx.WINDOW_SERVICE)).getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();

Yes, there are easier ways to retrieve the screen width on Android but there are cases that this long code is the only solution. You may already have the Context. WindowManager or the Display and so it would be smaller, but this code is more general.

PHP: array, all elements but first

Published by Silveira on 2011-03-09 
$bric = array("Brazil", "Russia", "India", "China"); 
$ric = $bric; // array copy
$br = array_shift($ric); // left shift at $ric. $br stores "Brazil" 
print_r($bric); // $bric remains the same
print_r($ric); // $ric lost "Brazil"

Output:

Array
(
    [0] => Brazil
    [1] => Russia
    [2] => India
    [3] => China
)
Array
(
    [0] => Russia
    [1] => India
    [2] => China
)
