Question

I am tring to do (like) a 2 dimensional array, case insensitive.

I have:

foreach ($rows as $key=>$row) { 
    $names[$key]=$row['Name']; 
} 

array_multisort($rows,SORT_STRING|SORT_FLAG_CASE,$names);

The above ends up producing the same result (with or without case flag).

Sick of staring at this, any ideas from somebody outside?

Answer 1

First of all SORT_FLAG_CASE is only available in PHP v5.4+ so I suggest checking which version of PHP you are running (maybe ‘uksort‘ could help if 5.3ish).

If not, make sure all the values that you put into $names lowercase or uppercase.

You have the order of the arguements $rows and $names reversed in the call to array_multisort.

Lastly if it comes from a database (or some other manner that means you cant change the data on the way into the array) then you can use array_walk.

Hope that helps
