mysqli_stmt::get_result
mysqli_stmt_get_result
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
mysqli_stmt::get_result -- mysqli_stmt_get_result — Gets a result set from a prepared statement as a mysqli_result object
Description
Object-oriented style
public mysqli_stmt::get_result(): mysqli_result|false
Procedural style
mysqli_stmt_get_result(mysqli_stmt $statement): mysqli_result|false
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.
Note:
Available only with mysqlnd.
Note:
This function cannot be used together with mysqli_stmt_store_result(). Both of these functions retrieve the full result set from the MySQL server.
Parameters
-
statement -
Procedural style only: A mysqli_stmt object returned by mysqli_stmt_init().
Return Values
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.
Examples
Example #1 Object-oriented style
<?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";
}
}
Example #2 Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_bind_param($stmt, "s", $continent);
$continentList= array('Europe', 'Africa', 'Asia', 'North America');
foreach ($continentList as $continent) {
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
while ($row = mysqli_fetch_array($result, MYSQLI_NUM)) {
foreach ($row as $r) {
print "$r ";
}
print "\n";
}
}
The above examples will output something similar to:
