mysqli_stmt::get_result

mysqli_stmt_get_result

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

mysqli_stmt::get_result -- mysqli_stmt_get_resultGets a result set from a prepared statement as a mysqli_result object

Description

Object-oriented style

publicmysqli_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.

Errors/Exceptions

If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR) and the requested operation fails, a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT, a mysqli_sql_exception is thrown instead.

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:

Albania 3401200 Europe Algeria 31471000 Africa Afghanistan 22720000 Asia Anguilla 8000 North America
