$arr = array();
while($ = mysql_fetch_array($sql)){
       $arr[] = array($r[col1]=> $r[col2]);

Your array structure is not clear. What do you mean by:
$row1["col1"]=>$row1["col2"]

It's PHP array syntax.

Your loop to retrieve the data from the data object is a bit of a mess:

PHP

while($ = mysql_fetch_array($sql)) {
       $arr[] = array($r[col1]=> $r[col2]);
  }

Unless you defined them as a fixed value, col1 and col2 are not valid indices. I suspect you left out the quotes (which you do use in yours what-you-want example.

I also suppose you meant $r and not just $ in you r while conditional test.

Also, if you wish to use one value as the array index, a guess at what you mean in the 'what I want' example, you'd likely want the content of the loop to look more like:

$arr[$r['col1']] = $r['col2']);

For a start.
