PHP Array Slice理解

Question

I have the following array:

Array

Array (
[0] => Array (
  ...
)
[41] => Array (
  [name] => London 
  [company] => nhyt6t
  [top25_1] => 8.75912088
)
[42] => Array (
  [name] => Manchester
  [company] => gtr4rf
  [top25_1] => 6.56758398
)
  ...
[75] => Array (
  [name] => Leeds
  [company] => de3wsd6
  [top25_1] => 7.58675398
)
)

If my reading and understanding of http://www.php.net/manual/en/function.array-slice.php is correct, then the following should return just those within the array with an index of between 40 and 65.

$array = array_slice($array, 40, 65);

However, in practise, what this does is remove Indexes 0 through 39 but leaves everything else.

Can anyone explained where I am going wrong?

Answer 1

Just try with:

$array = array_slice($array, 40, 65 - 40);

So:

$array = array_slice($array, 40, 25);

We start slicing from 40 position and get 25 elements (ending on 40+25=65 position).
