mysqli_stmt::num_rows

mysqli_stmt_num_rows

(PHP 5)

mysqli_stmt_num_rows — Return the number of rows in statements result set

Description

Object oriented style (property):

mysqli_stmt

int$num_rows;

Procedural style :

int mysqli_stmt_num_rows ( mysqli_stmt $stmt )

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 example will output:

Number of rows: 20.
