Currently, I have arrays like this:

Array (
[0] => Array (
[id] => 1,
[name] => "name",
[login] => "123456789"
),
[1] => Array (
[id] => 2,
[name] => "foo",
[login] => "987654321"
),
[2] => Array (
[id] => 3,
[name] => "bar",
[login] => "123454321"
)
)

and so on. What I want to do is arrange the first dimension-array by a key I specify that would be in the second dimension-array. For example, if I wanted it to sort by 'name,' it [the first dimension] would come out as 2, 1, 0, but the order of things in each second dimension would remain the same (id, name, login).

I've tried a lot of different ways to do this, and my last resort would be to code out 50 or so lines of breaking it down and sorting it manually, but I know this can be done by PHP. Does anyone know how?

Are you saying you want something like this?

Array (
[0] => Array (
[id] => 3,
[name] => "bar",
[login] => "123454321"
),
[1] => Array (
[id] => 1,
[name] => "name",
[login] => "123456789"
),
[2] =>Array (
[id] => 2,
[name] => "foo",
[login] => "987654321"
)
)

Bump...

I would like it if this question could be answered... I need it. I'm trying to sort a mysql result array by the zip code. If someone could answer this, I would be most grateful.

Thanks,
Josh

I'll work on it and get back to u soon.

Here you go:

PHP Code:

$myRay = Array (

'0' => Array (

'id' => 1,

'name' => "name",

'login' => "123456789"

),

'1' => Array (

'id' => 2,

'name' => "foo",

'login' => "987654321"

),

'2' => Array (

'id' => 3,

'name' => "bar",

'login' => "123454321"

)

);







function namecmp( $row1,$row2 )

{

    return strcmp($row1['login'], $row2['login']) ;

   

}

uasort($myRay,'namecmp');



echo "<pre>" ;

print_r( $myRay ) ;

echo "</pre>" ;

Thank you very much! That was exactly what I needed!

Is it possible to make this function descending instead of ascending order?

Code:

function namecmp( $row1,$row2 )
{
    return strcmp($row1['login'], $row2['login']) ;
   
}
uasort($myRay,'namecmp');
