how to use array_multisort

I have array like this:

300, 301, 302, 328, 329,
300, 301, 302, 328, 330,
300, 304, 305, 306,
300, 301, 303, 351,

and I need to make this array:
300, 304, 305, 306,
300, 301, 303, 351,
300, 301, 302, 328, 330,
300, 301, 302, 328, 329,

so rows are sorted by first higer walue in the row. Please help.
thanks

use the sort function like this:

$sorted = sort($array);

Thanks for reply, but I need to sort my array by columns and sort() doesnt work that.
It's like ORDER BY in SQL.

I don't know if this works or not, but give this a go:

$numbers = array ( "1" => array ( "300", "300", "300"), "2" => array ("300", "304", "303"), "3" => array ("303", "302", "300" ) );

Give you an array like this, in this order:
(**Inserted for formatting purposes)

1, 2, **3
300, 300, 303
300, 304, 302
300, 303, 300

Then, sort them however you want:

rsort($numbers);

Which would give you the new array like:

1, 2, **3
300, 304, 303
300, 303, 302
300, 300, 300

or by using the other sort methods:

asort, rsort, arsort, ksort, sort

Again, I don't know if this works I'm just trying to add some insight.

use array_multisort($array1,SORT_DESC,$array2);

that is how you order 2 arrays ie:

$array1 would have been:
5,1,6,2

$array2 would have been:
ted,albery,mary,smith

$array1 would now be 6,5,2,1
and $array2 would be mary,ted,smith,albery

hope this helps you in your direction
