He is still an outsider even though he has been involved in the battle of the airborne in Cretan.Along with the opening of the Soviet-German war, rude executed his first flight task in June 23, 1941. His outstanding flight technology earned him a first-level Iron Cross in July 18, 1941. In a September 23, 1941 air

Data Transformation
Since there is data in the workspace, the next step is data transformation. Statisticians and scientists usually remove unnecessary data from the analysis at this step. Let's first look at the data:

$arr =array(11=>2530,13=>8922,26=>250,77=>250,88=>1230,99=>12);
How can we retrieve the smallest three items of the above array:
array(99=>12,26=>250,77=>250)
Reply to discussion (solution)
$arr =array( 11=>2530, 13=>8922, 26=>250, 77=>250, 88=>1230, 99=>12);asort($arr);print_r(array_slice($arr, 0, 3, true));
