    <para>
     <function>array_slice</function> returns the sequence of elements
     from the array <parameter>array</parameter> as specified by the
     <parameter>offset</parameter> and <parameter>length</parameter>
     parameters.
    </para>
    <para>
     If <parameter>offset</parameter> is non-negative, the sequence will
     start at that offset in the <parameter>array</parameter>.  If
     <parameter>offset</parameter> is negative, the sequence will
     start that far from the end of the <parameter>array</parameter>.
    </para>
    <para>
     If <parameter>length</parameter> is given and is positive, then
     the sequence will have that many elements in it. If
     <parameter>length</parameter> 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 <parameter>offset</parameter> up until the end of the
     <parameter>array</parameter>.
    </para>
    <para>
     Note that <function>array_slice</function> will reset the array keys by
     default. Since PHP 5.0.2, you can change this behaviour by setting
     <parameter>preserve_keys</parameter> to &true;.
