Este método implementa um algoritmo de ordenação que ordena strings alfanuméricas
|
|
da maneira como um ser humano faria, mantendo associações chave/valor.
|
|
Isso é descrito como uma "ordem natural". Um exemplo da diferença
|
|
entre esse algoritmo e os algoritmos regulares de ordenação de strings de computador
|
|
(usados no método <link linkend="arrayobject.asort">ArrayObject::asort</link>)
|
|
pode ser visto no exemplo abaixo.
