mysqli_result::__construct — Constructs a mysqli_result object
This method constructs a new mysqli_result object.
It can be used to create the mysqli_result object after calling the mysqli_real_query() or mysqli_multi_query() function. Constructing the object manually is equivalent to calling the mysqli_store_result() or mysqli_use_result() function.
mysqlNur bei prozeduralem Aufruf: Ein von mysqli_connect() oder mysqli_init() zurückgegebenes mysqli-Objekt.
result_modeThe result mode can be one of 2 constants indicating how the result will be returned from the MySQL server.
MYSQLI_STORE_RESULT (default) - creates a
mysqli_result object with buffered result set.
MYSQLI_USE_RESULT - creates a
mysqli_result object with unbuffered result set.
As long as there are pending records waiting to be fetched, the
connection line will be busy and all subsequent calls will return error
Commands out of sync. To avoid the error all records
must be fetched from the server or the result set must be discarded by
calling mysqli_free_result(). The connection must
remain open for the rows to be fetched.
Beispiel #1 Creation of a mysqli_result object
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* Select queries return a result set */
$mysqli->real_query("SELECT Name FROM City LIMIT 10");
$result = new mysqli_result($mysqli);
printf("Select returned %d rows.\n", $result->num_rows);
Oben gezeigte Beispiele erzeugen eine ähnliche Ausgabe wie:
Select returned 10 rows.
