Q3Domain Verified
According to "The Complete PDO & Prepared Statements Course 2026", when using `PDOStatement::execute()` with a prepared statement that has both positional (?) and named (:name) placeholders, what is the recommended approach for binding these parameters to avoid ambiguity and potential errors?
Bind positional parameters first, followed by named parameters, using separate calls to `bindParam()` or `bindValue()`.
Mix positional and named placeholders within a single query, but ensure the parameter arrays passed to `execute()` are ordered correctly.
Use `PDOStatement::execute()` with an array that maps positional indices to named placeholders for complex statements.
Bind all parameters using only named placeholders for consistency.
