# mysqli_stmt_num_rows

(PHP 5)

mysqli_stmt_num_rows

(no version information, might be only in CVS)

stmt->num_rows -- Return the number of rows in statements result set

## Description

Procedural style :

mixed mysqli_stmt_num_rows ( mysqli_stmt stmt )

Object oriented style (property):

class mysqli_stmt {
int num_rows
}

Returns the number of rows in the result set. The use of mysqli_stmt_num_rows() depends on whether or not you used mysqli_stmt_store_result() to buffer the entire result set in the statement handle.

If you use mysqli_stmt_store_result(), mysqli_stmt_num_rows() may be called immediately.

## Rückgabewerte

An integer representing the number of rows in result set.

## Beispiele

Beispiel 1. Object oriented style
`<?php /* Open a connection */ $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20"; if ($stmt = $mysqli->prepare($query)) { /* execute query */ $stmt->execute(); /* store result */ $stmt->store_result(); printf("Number of rows: %d.\n", $stmt->num_rows); /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>`

Beispiel 2. Procedural style
`<?php /* Open a connection */ $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20"; if ($stmt = mysqli_prepare($link, $query)) { /* execute query */ mysqli_stmt_execute($stmt); /* store result */ mysqli_stmt_store_result($stmt); printf("Number of rows: %d.\n", mysqli_stmt_num_rows($stmt)); /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    Number of rows: 20.
