mysqli_stmt::$num_rows -- mysqli_stmt::num_rows -- mysqli_stmt_num_rows — Return the number of rows in statements result set
Object oriented style
public mysqli_stmt::num_rows ( ) : int
Procedural style
mysqli_stmt_num_rows ( mysqli_stmt $stmt ) : int
Returns the number of rows in the result set. The use of mysqli_stmt_num_rows() depends on whether or not you used mysqli_stmt_store_result() to buffer the entire result set in the statement handle.
If you use mysqli_stmt_store_result(), mysqli_stmt_num_rows() may be called immediately.
stmt
Procedural style only: A statement identifier returned by mysqli_stmt_init().
An integer representing the number of rows in result set.
Example #1 Object oriented style
<?php
/* Open a connection */
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20";
if ($stmt = $mysqli->prepare($query)) {
/* execute query */
$stmt->execute();
/* store result */
$stmt->store_result();
printf("Number of rows: %d.\n", $stmt->num_rows);
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
?> Example #2 Procedural style
<?php
/* Open a connection */
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20";
if ($stmt = mysqli_prepare($link, $query)) {
/* execute query */
mysqli_stmt_execute($stmt);
/* store result */
mysqli_stmt_store_result($stmt);
printf("Number of rows: %d.\n", mysqli_stmt_num_rows($stmt));
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
?> The above examples will output:
Number of rows: 20.
