Answer 1

 $i = 0

Warning: PDOStatement::bindValue(): SQLSTATE[HY093]: Invalid parameter number: Columns/Parameters are 1-based

This can also be confirmed from the PHP Manual

parameter

Parameter identifier. For a prepared statement using named placeholders, this will be a parameter name of the form :name. For a prepared statement using question mark placeholders, this will be the 1-indexed position of the parameter.
