<para>

<function>natsort</function> implémente un algorithme
|
|
de tri qui traite les chaînes alphanumériques du tableau
|
|
<parameter>array</parameter> comme un être humain tout en
|
|
conservant la relation clé/valeur. C'est ce qui est appelé
|
|
l'"ordre naturel". Un exemple de la différence de traitement
|
|
entre un tel algorithme et un algorithme de tri de chaînes
|
|
(comme lorsqu'on utilise <function>sort</function>) est
|
|
illustré ci-dessous.
