This is my problem:
I need to get four members of an array that have the maximum values of an attribute. I have seen the max() function already, but that one only gets me one member, and I need four. For example, I can have an array like this:

```
array( 
    array(
        "1", 
        "10"
    ), 
    array(
        "9", 
        "10"
    ), 
    array(
        "3", 
        "10"
    ), 
    array(
        "4", 
        "10"
    ), 
    array(
        "10", 
        "10"
    ), 
    array(
        "8", 
        "10"
    ), 
    array(
        "7", 
        "10"
    ), 
    array(
        "6", 
        "10"
    ), 
    array(
        "5", 
        "10"
    ), 
    array(
        "9", 
        "10"
    ) 
)

```

I need a function that will get me these four members:

> 
> array("10", "10"), array("9", "10"), array("8", "10"), array("7",
>  "10")
> 
> 
> 

Can anyone help?
