mysqli_result::$num_rows

mysqli_num_rows

(PHP 5)

mysqli_result::$num_rows -- mysqli_num_rowsGets the number of rows in a result

Description

Object oriented style

Procedural style

int mysqli_num_rows ( mysqli_result $result )

Returns the number of rows in the result set.

The behaviour of mysqli_num_rows() depends on whether buffered or unbuffered result sets are being used. For unbuffered result sets, mysqli_num_rows() will not return the correct number of rows until all the rows in the result have been retrieved.

Parameters

result

Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().

Return Values

Returns number of rows in the result set.

Note:

If the number of rows is greater than MAXINT, the number will be returned as a string.

Examples

Example #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();
?>

Example #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 will output:

 Result set has 239 rows.
