dynamic array multisort

[jug]

Hi,

 

Is there any way to pass dynamic arguments to array_multisort. Below is my idea of what the code should look like. First it has the data then its builds an array of array indexes with the sort direction. This array is then passed to the array_multisort function with the original data.

 

 

$data[] = array([0] => 67, [1] => 2, [3]' => 2001);$data[] = array([0] => 86, [1] => 4, [3]' => 2002);$data[] = array([0] => 98, [1] => 5, [3]' => 2002);$data[] = array([0] => 86, [1] => 6, [3]' => 2003);$data[] = array([0] => 67, [1] => 1, [3]' => 2004);$arg = array(1 => SORT_ASC, 3 => SORT_DESC);array_multisort($arg, $data);

 

 

I have got this working with hardcoded values, for example...

 

 

array_multisort($sort1, SORT_ASC, $sort3, SORT_DESC, $data);

 

 

but in my code instead of just 2 sorts there could be 'x' amounts.

 

I hope ive made this clear.

 

Any response would be much appreciated.

 

Thanks in advance.

You could use call_user_func_array to pass a dynamic array of parameters to the function.

thanks for your reply.

 

I did try that too but had no luck. In the end I settled for using eval. Not ideal but does the job.
