<function>natsort</function> implementa un algoritmo
|
|
de ordenación que trata las cadenas alfanuméricas del array
|
|
<parameter>array</parameter> como lo haría un ser humano,
|
|
conservando la relación clave/valor. Esto se conoce como
|
|
"orden natural". Un ejemplo de la diferencia de tratamiento
|
|
entre tal algoritmo y un algoritmo de ordenación de cadenas
|
|
(como cuando se utiliza <function>sort</function>) se ilustra a continuación.
