The PHP array_slice() function returns selected parts of an array.
If the optional preserve_keys is set to true, numeric keys are preserved. Non-numeric keys are not affected by this setting and will always be preserved.
<?php
$a = array('Car 1' => 'Lamborghini', 'Car 2' => 'Ferrari', 'Car 3' => 'Maserati');
print_r(array_slice($a, 1, 2));
?>
Output
Array ( [Car 2] => Ferrari [Car 3] => Maserati )
Syntax
array_slice(array, start, length, preserve_keys)
Parameters
| Parameter | Description |
|---|---|
| array | Specifies an array (required) |
| start | Specifies where the function will start the slice; 0 = the first element; if this value is set to a negative number, the function will start slicing from the last element (-2 would start at the second from the last element (required) |
| length | Specifies the length of the returned array; if this value is set to a negative number, the function will stop slicing that far from the last element; f this value is not set, the function will return all elements, starting from the position set by the start parameter |
| preserve_keys | Specifies if the function should preserve the numeric keys of the array or not; non-numeric keys are not affected by this setting and will always be preserved

PHP NOTES:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
