[Resolved] How do I...sort on a column of an associative array?

[s_shrum]

Here's how I am constructing my array:

...
$database_vars['match']++;
$file_array[$database_vars['match']]['name'] = $entry;
$file_array[$database_vars['match']]['length'] = $filename_length;
$file_array[$database_vars['match']]['base'] = $basename;
$file_array[$database_vars['match']]['ext'] = $ext;
$file_array[$database_vars['match']]['type'] = $type;
$file_array[$database_vars['match']]['size'] = $size;
...

So you get things like this:

$file_array[1]['name'] = "myfile.txt"
$file_array[1]['ext'] = "txt"
$file_array[1]['type'] = "file"
$file_array[1]['size] = "200"
$file_array[2]['name'] = "yourfile.txt"
$file_array[2]['ext'] = "txt"
$file_array[2]['type'] = "file"
$file_array[2]['size] = "140"
...

My question is, how do I sort on (either directly or indirectly with a function), let's say, the size key.

sort(), array_multisort(), etc? - see manual

Tried those....they do not work for this type of an array.

sort() works on single-dimensioned arrays

array_multisort() (if I read the manual correctly)works on sorting the individual arrays in a multi-dimensioned array. This explains why my attempts with this function are not working.

Doing things like:

array_multisort ($file_array[1]['name'],SORT_ASC,SORT_STRING);

fails...this is why I need 1) syntax example or 2) another way of dealing with this type of an array setup.

I need to be able to sort by element across each array, not just the individual values within an array record.

I take it you didn't read the whole of the [man]array_multisort[/man] page...

Found it....thanks.

Guess there is no built in way to handle it...

Oh well. 🙁
