I am trying to write a PHP-MySQL database processor that is somewhat intelligent. When this processor decides it needs to make an update, I want to report if it was really successful or not. I thought I could use mysql_affected_rows...

// Example:
// After running query "UPDATE mytable SET name='Test' WHERE ID=1"
$result = mysql_affected_rows();
if ($result >= 1) { /* Success */ }

If, for example, there was no row with ID=1, then $result would be 0.

However, it turns out that PHP's mysql_affected_rows is the actual affected rows, and may be still be 0 if the row exists but name was already "Test". (The PHP docs even say this is the case).

If I run this in the command line, I get the following meta information about the query:

Query OK, 0 rows affected (0.01 sec)
Rows matched: 1  Changed: 0  Warnings: 0

Is there any way for me to get that "Rows matched" value in PHP instead of the affected rows?
