Arrays with same element and grab one in php -


i have array consist of further sub arrays like

    array (     [0] => mm     [1] => cm     [2] => inch ) array (     [0] => mm     [1] => cm     [2] => inch )

since both arrays have same elements try fetch 1 that.i try array_unique(),merge function didn't succeed.i can remove 1 array using foreach loop want know if possible single statement, bulitin function or 1 line code not more that.hopes got point.i trying reduce code

if question, trying remove duplicate subarrays. try this

$input = array_map("unserialize", array_unique(array_map("serialize", $input)));

array_unique removes duplicates array.

array_map takes 2 arguments 

array_map ( callable $callback , array $arr1 [, array $... ] )

it recursively runs callback on array

basically code serializes array's content (each sub-array in case), removes duplicates unserialize content recreate original array
