The "i" parameter appears to be the row number. This was implied by checking mysql_result, which documents what the middle paramter specifies.
PHP - Manual: mssql_result
2024-11-15
(PHP 4, PHP 5, PECL odbtp >= 1.1.1)
mssql_result — Get result data
This function was REMOVED in PHP 7.0.0.
Alternatives to this function include:
mssql_result() returns the contents of one cell from a MS SQL result set.
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.
Note:
Specifying a numeric offset for the
field
argument is much quicker than specifying a fieldname or tablename.fieldname argument.
Returns the contents of the specified cell.
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);
?>
以上例程的输出类似于:

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:
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:
The "i" parameter appears to be the row number. This was implied by checking mysql_result, which documents what the middle paramter specifies.
