What potential issues can arise when using PDO bindParam in PHP for updating database entries?

When using PDO bindParam for updating database entries, one potential issue that can arise is that bindParam binds the variable by reference. This means that if you pass a variable that changes after binding but before executing the query, the updated value will be used in the query. To solve this issue, you can use bindValue instead of bindParam, as bindValue binds the variable by value, ensuring that the value at the time of binding is used in the query.

// Using bindValue instead of bindParam to update database entries
$value = 'new value';

$stmt = $pdo->prepare("UPDATE table SET column = :value WHERE id = :id");
$stmt->bindValue(':value', $value);
$stmt->bindValue(':id', $id);
$stmt->execute();
