The "array_slice" function is used to slice 0r extract elements from the array

    array_slice(array,start,length,preserve)

In the above syntax "array" specifies the array,"start" specifes where the function will start to splice, "length" specifes the total length of the slice, "preserve" if "true" else it will reset keys.

    <?php
    $b=array( 0 =>"Cherry",1 =>"Strawberry", 2 =>"Apple", 3 => "Orange");
    print_r(array_slice($b,1,2));
    ?>

    Array ( [1]=> Strawberry, [2]= Apple);

In the above example the array is sliced from the first element to length of second elements length totally.
