mysqli_result::$num_rows
mysqli_num_rows
Gets the number of rows in the result set

Description

Object-oriented style

int|string mysqli_result->num_rows ;

Procedural style

int|string 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. This function returns 0 for unbuffered result sets unless all rows have been fetched from the server.

Parameters

result: Procedural style only: A mysqli_result object returned by mysqli_query, mysqli_store_result, mysqli_use_result or mysqli_stmt_get_result.

Return Values

An int representing the number of fetched rows. Returns 0 in unbuffered mode unless all rows have been fetched from the server.

Note

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

Examples

Example 3.127 Object-oriented style

<?php

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

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

/* Get the number of rows in the result set */
$row_cnt = $result->num_rows;

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

Example 3.128 Procedural style

<?php

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

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

/* Get the number of rows in the result set */
$row_cnt = mysqli_num_rows($result);

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

The above examples will output:

Result set has 239 rows.
