Array function problems

The PHP array gives each element inside a date ("y-m-d", each element of the array); This function I forgot what to call. A new array is generated and then the Array_unique is removed and then the largest and the second one is written.

Array_map

$d = Array (' 1394591688 ', ' 1394591688 ', ' 1394581688 ', ' 1394491688 '), function  cube ($n) {    return date (' y-m-d ', $n ) ;} $b  =  array_map ("Cube",  $d), $b = Array_unique ($b); Var_dump ($b);

$d = Array (' 1394591688 ', ' 1394591688 ', ' 1394581688 ', ' 1394491688 '), function  cube ($n) {    return date (' y-m-d ', $n ) ;} $b  =  array_map ("Cube",  $d); Rsort ($b);//Reverse Sort $b = Array_unique ($b); Var_dump ($b [0]);//Largest Var_dump ($b [1] );//The second largest

Study, Array_map and array_unique two small functions, usually not how to use
