### Description

Object-oriented style

int|string $mysqli_stmt->num_rows;
public mysqli_stmt::num_rows(): int|string

Procedural style

mysqli_stmt_num_rows(mysqli_stmt `$statement`): int|string

Returns the number of rows buffered in the statement. This function will only work after mysqli_stmt_store_result() is called to buffer the entire result set in the statement handle.

This function returns `0` unless all rows have been fetched from the server.

### Parameters

`statement`

  Procedural style only: A mysqli_stmt object returned by mysqli_stmt_init().

### Return Values

An int representing the number of buffered rows. Returns `0` in unbuffered mode unless all rows have been fetched from the server.

> Note:

> If the number of rows is greater than `PHP_INT_MAX`, the number will be returned as a string.

### 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, CountryCode FROM City ORDER BY Name LIMIT 20";
$stmt = $mysqli->prepare($query);
$stmt->execute();
/* store the result in an internal buffer */
$stmt->store_result();
printf("Number of rows: %d.\n", $stmt->num_rows);`

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, CountryCode FROM City ORDER BY Name LIMIT 20";
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_execute($stmt);
/* store the result in an internal buffer */
mysqli_stmt_store_result($stmt);
printf("Number of rows: %d.\n", mysqli_stmt_num_rows($stmt));`

The above examples will output:

    Number of rows: 20.
