如何在php中表达DB2数据库的mysql_num_rows

Question

So I have a query that works with a DB2 database just fine as a part of my code.

Let's say it's something really simple like:

$sql = "SELECT * FROM Mytable";

How can I express the mysql_num_rows PHP function to work with a DB2 database ad not MySQL?

$numrows = mysql_num_rows($query);

Answer 1

There is a corresponding db2_num_rows() function if you enable the db2 extension for php.
