mysqli_stmt::__construct — Constructs a new mysqli_stmt object
$link
[, string $query
] )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.
link
仅以过程化样式:由 mysqli_connect() 或 mysqli_init() 返回的链接标识。
query
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() .
