PHP - Function array_slice()



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

Definition and Usage

The 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.


Parameter Description
array Required. Specifies an array.
offset Required. Numeric value. Specifies where the function will start the slice.
length Optional. Numeric value. Specifies the length of the slice.
preserve_keys Optional. TRUE to preserve keys and FALSE to reset keys. Default is FALSE.

Return Values

Returns the sequence of elements.


Try out following example −

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

This will produce the following result −

Array ( [0] => c [1] => d ) Array ( [2] => c [3] => d )
