mysqli_num_rows
(PHP 5)
mysqli_num_rows --
Gets the number of rows in a result
Description
Procedural 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.
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

/* 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); ?>
