PHP Mysqli::get_result() Method: Usage and Examples

Retrieves buffered result rows from a prepared statement as a mysqli_result.

The examples focus on the operation itself, including the important distinction: mysqli_stmt::fetch accesses bound output variables instead.

What It Does

Use the examples below to observe the behavior on a small dataset before extending it to application code.

Syntax and Return Value

Not an API method: use mysqli_stmt::get_result() instead

The displayed signature describes the API or identifies any correction or optional dependency. When a parameter is optional, supply it only when the task requires it.

Example 1: Basic Use

Important correction: mysqli::get_result() does not exist. The actual method is mysqli_stmt::get_result(), called on a prepared statement; mysqlnd is required.

<?php
$mysqli = new mysqli(getenv('DB_HOST') ?: '127.0.0.1', getenv('DB_USER') ?: 'app', getenv('DB_PASSWORD') ?: '', getenv('DB_NAME') ?: 'demo');
$mysqli->set_charset('utf8mb4');
$selectedId = 7;
$statement = $mysqli->prepare('SELECT email FROM users WHERE id = ?');
$statement->bind_param("i", $selectedId);
$statement->execute();
$result = $statement->get_result();
echo json_encode($result->fetch_assoc());

This example is meant for a configured application environment; output depends on the installed extension, external service, or database contents.

Example 2: Checking Behavior

Important correction: mysqli::get_result() does not exist. The actual method is mysqli_stmt::get_result(), called on a prepared statement; mysqlnd is required.

<?php
$mysqli = new mysqli(getenv('DB_HOST') ?: '127.0.0.1', getenv('DB_USER') ?: 'app', getenv('DB_PASSWORD') ?: '', getenv('DB_NAME') ?: 'demo');
$mysqli->set_charset('utf8mb4');
$selectedId = 12;
$statement = $mysqli->prepare('SELECT email FROM users WHERE id = ?');
$statement->bind_param("i", $selectedId);
$statement->execute();
$result = $statement->get_result();
echo json_encode($result->fetch_assoc());

This example is meant for a configured application environment; output depends on the installed extension, external service, or database contents.

Example 3: Practical Example

Important correction: mysqli::get_result() does not exist. The actual method is mysqli_stmt::get_result(), called on a prepared statement; mysqlnd is required.

<?php
$mysqli = new mysqli(getenv('DB_HOST') ?: '127.0.0.1', getenv('DB_USER') ?: 'app', getenv('DB_PASSWORD') ?: '', getenv('DB_NAME') ?: 'demo');
$mysqli->set_charset('utf8mb4');
$selectedId = 24;
$statement = $mysqli->prepare('SELECT email FROM users WHERE id = ?');
$statement->bind_param("i", $selectedId);
$statement->execute();
$result = $statement->get_result();
echo json_encode($result->fetch_assoc());

This example is meant for a configured application environment; output depends on the installed extension, external service, or database contents.

Important Behavior and Edge Cases

Requires mysqlnd and a statement that produces a result set; use bind_result where unsupported.

There is no method named mysqli::get_result(). Calling it on a mysqli connection raises an Error. Use mysqli_stmt::get_result() after preparing and executing the statement; mysqlnd is required.

Key Takeaways

• Retrieves buffered result rows from a prepared statement as a mysqli_result.
• Requires mysqlnd and a statement that produces a result set; use bind_result where unsupported.
• mysqli_stmt::fetch accesses bound output variables instead.

Use Mysqli::get_result when its documented behavior matches the problem. Test the relevant edge cases in your own runtime before deploying it.
