说明
$stmt
)Makes the next result of the specified statement active. Results include result sets, row counts, and output parameters.

返回值
Returns TRUE if the next result was successfully retrieved, FALSE if an error
occurred, and NULL if there are no more results to retrieve.
范例
Example #1 sqlsrv_next_result() example
The following example executes a batch query that inserts into a table and then selects from the table. This produces two results on the statement: one for the rows affected by the INSERT and one for the rows returned by the SELECT. To get to the rows returned by the SELECT, sqlsrv_next_result() must be called to move past the first result.
<?php
$serverName = "serverName\sqlexpress" ;
$connectionInfo = array( "Database" => "dbName" , "UID" => "userName" , "PWD" => "password" );
$conn = sqlsrv_connect ( $serverName , $connectionInfo );
$query = "INSERT INTO Table_1 (id, data) VALUES (?,?); SELECT * FROM TABLE_1;" ;
$params = array( 1 , "some data" );
$stmt = sqlsrv_query ( $conn , $query , $params );
// Consume the first result (rows affected by INSERT) without calling sqlsrv_next_result.
echo "Rows affected: " . sqlsrv_rows_affected ( $stmt ). "<br />" ;
// Move to the next result and display results.
$next_result = sqlsrv_next_result ( $stmt );
if( $next_result ) {
while( $row = sqlsrv_fetch_array ( $stmt , SQLSRV_FETCH_ASSOC )){
echo $row [ 'id' ]. ": " . $row [ 'data' ]. "<br />" ;
}
} elseif( is_null ( $next_result )) {
echo "No more results.<br />" ;
} else {
die( print_r ( sqlsrv_errors (), true ));
}

You can use a for loop to iterate through the results:
If you know how many results there should be it's easier, otherwise you can put a large number in the loop constructor and break when done:
<?php
for ($i=0; $i< (Large # or Exact #); $i++)
{
$rows_affected = sqlsrv_rows_affected($q2);
if ($rows_affected === false)
{
echo 'Inserts Failed<br />\n';
} else if ( $rows_affected == -1) {
echo "No information available.<br />\n";
} else {
echo $rows_affected." rows were added.<br />\n";
}
$next_result = sqlsrv_next_result($q2);
if (!$next_result)
{
break;
}
}
?>
