Description
int
mysql_num_rows ( resource result)
mysql_num_rows() returns the number of rows in a result set. This command is only valid for SELECT statements. To retrieve the number of rows affected by a INSERT, UPDATE or DELETE query, use mysql_affected_rows().
Example 1. mysql_num_rows() example <?php
$link = mysql_connect("localhost", "mysql_user", "mysql_password");
mysql_select_db("database", $link);
$result = mysql_query("SELECT * FROM table1", $link);
$num_rows = mysql_num_rows($result);
echo "$num_rows Rows\n";
?> |
|
Note: If you use mysql_unbuffered_query(), mysql_num_rows() will not return the correct value until all the rows in the result set have been retrieved.
See also mysql_affected_rows(), mysql_connect(), mysql_data_seek(), mysql_select_db() and mysql_query().
For downward compatibility mysql_numrows() can also be used. This is deprecated however.
