What is the difference between bindParam and bindValue?

Question

What is the difference between PDOStatement::bindParam() and PDOStatement::bindValue()?

Answer 1

From Prepared statements and stored procedures

Use bindParam to insert multiple rows with one time binding:

prepare("INSERT INTO REGISTRY (name, value) VALUES (?, ?)");
$stmt->bindParam(1, $name);
$stmt->bindParam(2, $value);

// insert one row
$name = 'one';
$value = 1;
$stmt->execute();

// insert another row with different values
$name = 'two';
$value = 2;
$stmt->execute();
