使用PHP的输出参数调用SQL Server存储过程

$serverName = "server_name";
$connectionOptions = array(
    "Database" => "database_name",
    "Uid" => "username",
    "PWD" => "password"
);

$conn = sqlsrv_connect($serverName, $connectionOptions);
if ($conn === false) {
    die(print_r(sqlsrv_errors(), true));
}

$procedureName = "{call stored_procedure_name(?, ?)}";

$inputParam1 = "input_value";
$inputParam2 = "input_value";

$outputParam1 = null;
$outputParam2 = null;

$stmt = sqlsrv_prepare($conn, $procedureName, array(&$inputParam1, &$inputParam2, &$outputParam1, &$outputParam2));
if ($stmt === false) {
    die(print_r(sqlsrv_errors(), true));
}

if (sqlsrv_execute($stmt) === false) {
    die(print_r(sqlsrv_errors(), true));
}

echo "Output Parameter 1: " . $outputParam1 . "<br>";
echo "Output Parameter 2: " . $outputParam2 . "<br>";
