array_slice returns the sequence of elements
from the array array as specified by the
offset and length
parameters.
&reftitle.parameters;
array
The input array.
offset
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.
length
If length is given and is positive, then
the sequence will have up to that many elements in it. If the array
is shorter than the length, then only the
available array elements will be present. 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.
preserve_keys
Note that array_slice will reorder and reset the
numeric array indices by default. You can change this behaviour by setting
preserve_keys to &true;.
&reftitle.returnvalues;
Returns the slice.

&Version;
&Description;
5.2.4
The default value of the length parameter was changed to NULL. A NULL length now tells the function to use the length of array. Prior to this version, a NULL length was taken to mean a zero length (nothing will be returned).
5.0.2
The optional preserve_keys parameter was added.
