mysqli_stmt::get_result -- mysqli_stmt_get_result — Gets a result set from a prepared statement as a mysqli_result object
Об'єктно-орієнтований стиль
Процедурний стиль
Retrieves a result set from a prepared statement as a mysqli_result object. The data will be fetched from the MySQL server to PHP. This method should be called only for queries which produce a result set.
Зауваження:
Доступно тільки з mysqlnd.
Зауваження:
This function cannot be used together with mysqli_stmt_store_result(). Both of these functions retrieve the full result set from the MySQL server.
statementТільки процедурний стиль: об'єкт mysqli_stmt, якого повертає функція mysqli_stmt_init().
Returns false on failure. For successful queries which produce a result set, such as SELECT, SHOW, DESCRIBE or
EXPLAIN, mysqli_stmt_get_result() will return
a mysqli_result object. For other successful queries, mysqli_stmt_get_result() will
return false. The mysqli_stmt_errno() function can be
used to distinguish between the two reasons for false; due to a bug, prior to PHP 7.4.13,
mysqli_errno() had to be used for this purpose.
Якщо увімкнені звіти про помилки
mysqli (MYSQLI_REPORT_ERROR) і запитана операція не
виконалась, буде виведено попередження, але якщо встановлено режим
MYSQLI_REPORT_STRICT, буде викинуто виключення
mysqli_sql_exception.
Приклад #1 Об'єктно-орієнтований стиль
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";
$stmt = $mysqli->prepare($query);
$stmt->bind_param("s", $continent);
$continentList = array('Europe', 'Africa', 'Asia', 'North America');
foreach ($continentList as $continent) {
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_array(MYSQLI_NUM)) {
foreach ($row as $r) {
print "$r ";
}
print "\n";
}
}Приклад #2 Процедурний стиль
