• mysqli_stmt::get_result

  mysqli_stmt_get_result

  Gets a result set from a prepared statement

Description

Object oriented style

public mysqli_result|false mysqli_stmt::get_result();

Procedural style

mysqli_result|false mysqli_stmt_get_result(mysqli_stmt statement);

Call to return a result set from a prepared statement query.

Parameters

stmt

Procedural style only: A statement identifier 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.

MySQL Native Driver Only

Available only with mysqlnd.

Examples

Example 7.95 Object oriented style

<?php 
$mysqli = new mysqli("127.0.0.1", "user", "password", "world"); 
if($mysqli->connect_error)
{
    die("$mysqli->connect_errno: $mysqli->connect_error");
}
$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";
$stmt = $mysqli->stmt_init();
if(!$stmt->prepare($query))
{
    print "Failed to prepare statement\n";
}
else
{
    $stmt->bind_param("s", $continent);
    $continent_array = array('Europe','Africa','Asia','North America');
    foreach($continent_array as $continent)
    {
        $stmt->execute();
        $result = $stmt->get_result();
        while ($row = $result->fetch_array(MYSQLI_NUM))
        {
            foreach ($row as $r)
            {
                print "$r ";
            }
            print "\n";
        }
    }
}
$stmt->close();
$mysqli->close();
?>

Example 7.96 Procedural style

<?php 
$link = mysqli_connect("127.0.0.1", "user", "password", "world"); 
if (!$link)
{
    $error = mysqli_connect_error();
    $errno = mysqli_connect_errno();
    print "$errno: $error\n";
    exit();
}
$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";
$stmt = mysqli_stmt_init($link);
if(!mysqli_stmt_prepare($stmt, $query))
{
    print "Failed to prepare statement\n";
}
else
{
    mysqli_stmt_bind_param($stmt, "s", $continent);
    $continent_array = array('Europe','Africa','Asia','North America');
    foreach($continent_array 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";
        }
    }
}
mysqli_stmt_close($stmt);
mysqli_close($link);
?>

The above examples will output:
