A more object oriented way would be to provide a range to the     method   For instance   Say you want the first 3 items from an array   numbers    1 2 3 4 5 6   numbers 0  2        1 2 3   Say you want the first x items from an array   numbers 0  x-1   The great thing about this method is if you ask for more items than the array has  it simply returns the entire array   numbers 0  100        1 2 3 4 5 6

array splice     Remove a portion of the array and replace it with something else    input   array 1  2  3  4  5  6   array splice  input  5       input is now array 1  2  3  4  5    From PHP manual   array array splice   array  amp  input   int  offset    int  length   0    mixed  replacement      If length is omitted  removes everything from offset to the end of the array  If length is specified and is positive  then that many elements will be removed  If length is specified and is negative then the end of the removed portion will be that many elements from the end of the array  Tip  to remove everything from offset to the end of the array when replacement is also specified  use count  input  for length

You can use array slice function  but do you will use  another values  or only the first 5  because if you will use only the first 5 you can use the LIMIT on SQL

If you just want to output the first 5 elements  you should write something like    lt  php    if   empty    an array             min   min   count    an array    5          i   0       foreach   value in  an array           echo  value         i          if   i     min  break                 gt    If you want to write a function which returns part of the array  you should use array slice    lt  php    function GetElements   an array   elements         return array slice   an array  0   elements           gt
