public bool mysqli_stmt::fetch();

Procedural style

bool mysqli_stmt_fetch(mysqli_stmt stmt);

Fetch the result from a prepared statement into the variables bound by mysqli_stmt_bind_result.

Note

Note that all columns must be bound by the application before calling mysqli_stmt_fetch.

Note

Data are transferred unbuffered without calling mysqli_stmt_store_result which can decrease performance (but reduces memory cost).

$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 150,5";
if ($stmt = $mysqli->prepare($query)) {
