mysqli_num_rows

(PHP 5)

mysqli_num_rows -- Gets the number of rows in a result

Description

Procedural style:

mixed mysqli_num_rows ( object result)

Object oriented style (property):

class mysqli {

mixed num_rows

}

Returns the number of rows in the result set.

The use of mysqli_num_rows() depends on whether you use buffered or unbuffered result sets. In case you use unbuffered resultsets mysqli_num_rows() will not correct the correct number of rows until all the rows in the result have been retrieved.

Return values

Returns number of rows in the result set.

Notã: If the number of rows is greater than maximal int value, the number will be returned as a string.

Example

Exemplu 1. Object oriented style


<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

if ($result = $mysqli->query("SELECT Code, Name FROM Country ORDER BY Name")) {

    /* determine number of rows result set */
    $row_cnt = $result->num_rows;

    printf("Result set has %d rows.\n", $row_cnt);

    /* close result set */
    $result->close();
}

/* close connection */
$mysqli->close();
?>

Exemplu 2. Procedural style


<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

if ($result = mysqli_query($link, "SELECT Code, Name FROM Country ORDER BY Name")) {

    /* determine number of rows result set */
    $row_cnt = mysqli_num_rows($result);

    printf("Result set has %d rows.\n", $row_cnt);

    /* close result set */
    mysqli_free_result($result);
}

/* close connection */
mysqli_close($link);
?>

The above examples would produce the following output:

Result set has 239 rows.
