How can the error message "Invalid parameter number: parameter was not defined" be resolved when using bindParam in PDO for SQL Server access in PHP?

The error "Invalid parameter number: parameter was not defined" occurs when the number of parameters in the SQL query does not match the number of placeholders in the bindParam function. To resolve this issue, ensure that the number of parameters passed to bindParam matches the number of placeholders in the query. 

// Correct way to bind parameters in PDO for SQL Server access in PHP
$stmt = $pdo->prepare("SELECT * FROM table WHERE column1 = :param1 AND column2 = :param2");
$stmt->bindParam(':param1', $param1);
$stmt->bindParam(':param2', $param2);
$stmt->execute();
