mysqli_num_rows (PHP 5) mysqli_num_rows --
Gets the number of rows in a result
DescriptionProcedural style: int mysqli_num_rows ( mysqli_result result ) Object oriented style (property): class mysqli_result { int 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.
Note:
If the number of rows is greater than maximal int value, the number
will be returned as a string.
ExamplesExample 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);
