Esta función ordenará las claves de una matriz utilizando una función
|
|
de comparación suministrada por el usuario. Si la matriz a ordenar
|
|
necesita utilizar un criterio poco trivial, esta es la función que
|
|
deberá usar.

|
|
Function <parameter>cmp_function</parameter> should accept two
|
|
parameters which will be filled by pairs of <parameter>array</parameter> keys.
|
|
The comparison function must return an integer less than, equal
|
|
to, or greater than zero if the first argument is considered to
|
|
be respectively less than, equal to, or greater than the
|
|
second.
