php - How to remove duplicates and the original one from a multidimensional array? -


how can delete duplicates in multidimensional array? tried several answers found on stackoverflow none of them works me in multi array. closest answer found this:

how delete duplicates in array? worked on single-dimensional array.

for example have this:

$array = array(     [0] = array(         [color] => red,         [type] => color,         [name] => color1     )     [1] = array(         [color] => gray,         [type] => color,         [name] => color2     )     [2] = array(         [color] => blue,         [type] => color,         [name] => color3     )     [3] = array(         [color] => green,         [type] => color,         [name] => color4     )     [4] = array(         [color] => black,         [type] => color,         [name] => color5     )     [3] = array(         [color] => gray,         [type] => color,         [name] => color2     )     [4] = array(         [color] => blue,         [type] => color,         [name] => color3     ) )

how can let become this:?

$array = array(     [0] = array(         [color] => red,         [type] => color,         [name] => color1     )     [1] = array(         [color] => gray,         [type] => color,         [name] => color2     )     [2] = array(         [color] => blue,         [type] => color,         [name] => color3     )     [3] = array(         [color] => green,         [type] => color,         [name] => color4     )     [4] = array(         [color] => black,         [type] => color,         [name] => color5     ) )

well, poor answer appears want unique data, here's bad code solve this.

$array2 = array(); foreach ($array $val)  {   @$array2[$val['color']]++; } foreach ($array $key=>$val)  {   if ($array2[$val['color']] >1)    unset($array[$key]); }

the @ there prevent php throwing error. or can write more code predefine $array2 work.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
