Binds a variable to a column in a result set.

bool PDOStatement::bindColumn($column, &$param[, $type[, $maxLen[, $driverdata ]]] );

$column: The (mixed) number of the column (1-based index) or name of the column in the result set.

&$param: The (mixed) name of the PHP variable to which the column will be bound.

$type: The optional data type of the parameter, represented by a PDO::PARAM_* constant.

$maxLen: Optional integer, not used by the SQL Server for PHP driver.

$driverdata: Optional mixed parameter(s) for the driver. For example, you could specify PDO::SQLSRV_ENCODING_UTF8 to bind the column to a variable as a string encoded in UTF-8.

TRUE if success, otherwise FALSE.

Support for PDO was added in version 2.0 of the Microsoft Drivers for PHP for SQL Server.

This example shows how a variable can be bound to a column in a result set.

$database = "AdventureWorks";
$server = "(local)";
$conn = new PDO( "sqlsrv:server=$server ; Database = $database", "", "");

$query = "SELECT Title, FirstName, EmailAddress FROM Person.Contact where LastName = 'Estes'";
$stmt = $conn->prepare($query);

$stmt->bindColumn('EmailAddress', $email);
while ( $row = $stmt->fetch( PDO::FETCH_BOUND ) ){
   echo "$email\n";
