Syntax

array_slice($array, $offset [,$length [,$preserve_keys]] );

Definition and Usage

Thsi function returns the sequence of elements from the array array as specified by the offset and length parameters.

If offset is non-negative, the sequence will start at that offset in the array. If offset is negative, the sequence will start that far from the end of the array.

If length is given and is positive, then the sequence will have that many elements in it. If length is given and is negative then the sequence will stop that many elements from the end of the array. If it is omitted, then the sequence will have everything from offset up until the end of the array.

Paramters

ParameterDescription
arrayRequired. Specifies an array.
offsetRequired. Numeric value. Specifies where the function will start the slice.
lenghtOptional. Numeric value. Specifies the length of the slice.
preserve_keysOptional. TRUE to preserve keys and FALSE to reset keys. Default is FALASE.

$input = array("a", "b", "c", "d", "e");
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));
?> 

This will produce following result:
