Verifying the execute boolean status or utilizing try/catch with PDO

Apologies for the subpar title. My project heavily relies on AJAX, with most responses returning either 'error' or 'success' messages in an array. In my Javascript code, I display these messages in a custom notification bar.

I'm unsure about the best practice for handling errors. When it comes to checking the PDO query for success or failure in the return array, I don't know whether to rely on the boolean value returned by execute(), or if I should implement a try/catch block.

Is there a significant difference in error handling methods?

Answer №1

There isn't much of a distinction in this scenario, but it's worth checking for PDOStatement->execute().

Sometimes when you're updating or deleting rows and your PDOStatement->execute() returns true even if no rows met the specified conditions, it's because no error occurred. In such situations, using PDOStatement->rowCount() can help determine how many rows were actually affected.

Note: It's not advisable to solely depend on PDOStatement->rowCount() for select statements as:

If the last SQL statement performed by the associated PDOStatement was a SELECT query, some databases might provide the number of rows returned by that query. However, this behavior is not consistent across all databases and should not be relied upon for universal applications.
