The "i" parameter appears to be the row number. This was implied by checking mysql_result, which documents what the middle paramter specifies.
mssql_result
(PHP 4, PHP 5, PECL odbtp >= 1.1.1)
mssql_result — Get result data
Avertizare
Această funcție a fost ELIMINATĂ în PHP 7.0.0.
Variante alternative pentru această funcție sunt:
Descrierea
mssql_result() returns the contents of one cell from a MS SQL result set.
Parametri
-
result -
The result resource that is being evaluated. This result comes from a call to mssql_query().
-
row -
The row number.
-
field -
Can be the field's offset, the field's name or the field's table dot field's name (tablename.fieldname). If the column name has been aliased ('select foo as bar from...'), it uses the alias instead of the column name.
Notă:
Specifying a numeric offset for the
fieldargument is much quicker than specifying afieldnameortablename.fieldnameargument.
Valorile întoarse
Returns the contents of the specified cell.
Exemple
Example #1 mssql_result() example
<?php
// Send a select query to MSSQL
$query = mssql_query('SELECT [username] FROM [php].[dbo].[userlist]');
// Check if there were any records
if (!mssql_num_rows($query)) {
echo 'No records found';
} else {
for ($i = 0; $i < mssql_num_rows($query); ++$i) {
echo mssql_result($query, $i, 'username'), PHP_EOL;
}
}
// Free the query result
mssql_free_result($query);
?>

Example #2 Faster alternative to above example
<?php
// Send a select query to MSSQL
$query = mssql_query('SELECT [username] FROM [php].[dbo].[userlist]');
// Check if there were any records
if (!mssql_num_rows($query)) {
echo 'No records found';
} else {
while ($row = mssql_fetch_array($query)) {
echo $row['username'], PHP_EOL;
}
}
// Free the query result
mssql_free_result($query);
?>
Note
Notă:
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker than mssql_result().

Recommended high-performance alternatives:
- mssql_fetch_row() - Get row as enumerated array
- mssql_fetch_array() - Fetch a result row as an associative array, a numeric array, or both
- mssql_fetch_assoc() - Returns an associative array of the current row in the result
- mssql_fetch_object() - Fetch row as object
