mysqli_stmt::$num_rows -- mysqli_stmt::num_rows -- mysqli_stmt_num_rows — Return the number of rows in statements result set

Description

Object oriented style

int $mysqli_stmt->num_rows;

public mysqli_stmt::num_rows ( ) : int

Procedural style

mysqli_stmt_num_rows ( mysqli_stmt $stmt ) : int

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.

Parameters

stmt: Procedural style only: A statement identifier returned by mysqli_stmt_init().

Return Values

An integer representing the number of rows in result set.

Examples

Example #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();?>

Example #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);?>

The above examples will output:

Number of rows: 20.
