Help sorting array

[TheBiff]

I need help sorting an array.  Here is an example of what it looks like:

 

$data[w-99-893] = array('text',array('a'=>'12','b'=>'12'),'M');

$data[w-68-e02] = array('text',array('a'=>'16','b'=>'14'),'M');

$data[w-95-102] = array('text',array('a'=>'10','b'=>'11'),'M');

 

I need to sort by that first key (w-99-893,w-68-e02,w-95-102). All of the standard php functions don't seem to do it.  I keep getting 1 as an output. 

 

Any ideas?

 

Thanks.

Something like ksort or krsort should be what you need.

They output 1.

But the array will be sorted (it's passed by reference, not by value). The 1 indicates boolean true- the sort was successful.

 

Orio.

Great. Thanks.

 

Instead of doing ksort($data) i was doing $data=ksort($data). 

 

It's been a long day. 

 

Thanks!
