Copy the code The code is as follows:
/*
Use the example in the manual
* /
$input = array ("a", "b", "c", "d", "e");
$output = array_slice ($input, 2); // returns "c" , "d", and "e",
$output = array_slice ($input, 2, -1); // returns "c", "d"
$output = array_slice ($input, -2 , 1); // returns "d"
$output = array_slice ($input, 0, 3); // returns "a", "b", and "c"
?>
The important point is that length is negative. It means taking the array until it is as far as length from the end of the array
