<function>array_chunk</function> divide una matriz en varias matrices, cada una con
|
|
un número de valores equivalente a <parameter>size</parameter>. La
|
|
última matriz generada puede tener un número menor de valores.
|
|
Las matrices se obtienen como miembros de una matriz multidimensional, que
|
|
será indexada con números empezando por el cero.

|
Si al parámetro opcional <parameter>preserve_keys</parameter> se
|
|
le da el valor de &true;, se fuerza a PHP a preservar las claves originales
|
|
de la matriz de entrada. Si se especifica &false;, se utilizarán
|
|
nuevos índices numéricos en cada matriz resultante. El valor
|
|
por defecto es &false;.
