mysqli_stmt::__construct

This method constructs a new mysqli_stmt object.

Note:

In general, you should use either mysqli_prepare() or mysqli_stmt_init() to create a mysqli_stmt object, rather than directly instantiating the object with new mysqli_stmt. This method (and the ability to directly instantiate mysqli_stmt objects) may be deprecated and removed in the future.

Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()

The query, as a string. If this parameter is omitted, then the constructor behaves identically to mysqli_stmt_init(), if provided, then it behaves as per mysqli_prepare().
