3.10.20. `mysqli_stmt::$num_rows`, `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 ;

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 3.93. 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 3.94. 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);
?>
