  • 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_result|false mysqli_stmt::get_result();

Procedural style

mysqli_result|false mysqli_stmt_get_result(mysqli_stmt statement);

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 7.96 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 7.97 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
