<para>
<function>array_chunk</function> splits the array into
several arrays with <parameter>size</parameter> values
in them. You may also have an array with less values
at the end. You get the arrays as members of a
multidimensional array indexed with numbers starting
from zero.
</para>
<para>
By setting the optional <parameter>preserve_keys</parameter>
parameter to &true;, you can force PHP to preserve the original
keys from the input array. If you specify &false; new number
indicies will be used in each resulting array with
indices starting from zero. The default is &false;.
