This topic and the topics in this section discuss how to retrieve data.

The SQLSRV driver of the Microsoft Drivers for PHP for SQL Server provides the following options for retrieving data from a result set:

• sqlsrv_fetch_array

• sqlsrv_fetch_object

• sqlsrv_fetch/sqlsrv_get_field

Note

When you use any of the functions mentioned above, avoid null comparisons as the criterion for exiting loops. Because sqlsrv functions return false when an error occurs, the following code could result in an infinite loop upon an error in sqlsrv_fetch_array: /* This code could result in an infinite loop. It is recommended that you do NOT use null comparisons as the criterion for exiting loops, as is done here. */ do{ $result = sqlsrv_fetch_array($stmt); } while( !is_null($result));

If your query retrieves more than one result set, you can move to the next result set with sqlsrv_next_result.

Beginning in version 1.1 of the Microsoft Drivers for PHP for SQL Server, you can use sqlsrv_has_rows to see if a result set has rows.

The PDO_SQLSRV driver of the Microsoft Drivers for PHP for SQL Server provides the following options for retrieving data from a result set:

• PDOStatement::fetch

• PDOStatement::fetchAll

• PDOStatement::fetchColumn

• PDOStatement::fetchObject

If your query retrieves more than one result set, you can move to the next result set with PDOStatement::nextRowset.

You can see how many rows are in a result set if you specify a scrollable cursor, and then call PDOStatement::rowCount.

PDO::prepare lets you specify a cursor type. Then, with PDOStatement::fetch you can select a row. See PDO::prepare for a sample and more information.
