Description:
------------
function.odbc-field-name does not respect the AS function in a SELECT statement shown below:

$query_db_CDR = "SELECT	tbl_EM_Matrix.hostname as vru from ..."

The result, returns 'hostname', instead of 'vru'.

Reproduce code:
---------------
---
From manual page: function.odbc-field-name
---

function odbc_fetch_assoc($result){
	if (odbc_fetch_row($result)) {
		$return_array=array();
		$max_result=odbc_num_fields($result);
	
		for ($counter=1;$counter<=$max_result;$counter++){
			$return_array[odbc_field_name($result, $counter)] = odbc_result($result, $counter);
		}
				
		return $return_array; 		
	}
}

Expected result:
----------------
Using the select statement from above, I should be able to print_r (odbc_fetch_assoc($result)), and see 'vru'.  Instead, I see 'hostname'.  The function does not respect the "as" function.

Array ([hostname]=>)

Actual result:
--------------
Array ([vru]=>)
