mysqli_num_rows
MYSQLI_NUM_ROWS(3) 1 MYSQLI_NUM_ROWS(3)mysqli_result::$num_rows - Gets the number of rows in a result
Object oriented style
SYNOPSIS
int$mysqli_result->num_rows ()
DESCRIPTION
Procedural style
int mysqli_num_rows (mysqli_result $result)
Returns the number of rows in the result set.
The behaviour of mysqli_num_rows(3) depends on whether buffered or unbuffered result sets are being used. For unbuffered result sets,
mysqli_num_rows(3) will not return the correct number of rows until all the rows in the result have been retrieved.
PARAMETERS
o $
result -Procedural style only: A result set identifier returned by mysqli_query(3), mysqli_store_result(3) or
mysqli_use_result(3).
RETURN VALUES
Returns number of rows in the result set.
Note
If the number of rows is greater than PHP_INT_MAX, the number will be returned as a string.
EXAMPLES
Example #1
Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
if ($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.
", $row_cnt);
/* close result set */
$result->close();
}
/* close connection */
$mysqli->close();
?>
Example #2
Procedural style
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
if ($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.
", $row_cnt);
/* close result set */
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
The above examples will output:
Result set has 239 rows.
