Maybe you'll remember this bug now, lyric? =)

The code as written will not even give you that. If you're posting a bug report, please
cut'n'paste the sample code - we can't help if you don't describe your problem
properly :)
Anyway, your code is broken :
- the for loop should be seperated by ; not ,
- The parameter to sybase_fetch_row() should be $result not $row
Your problem is that sybase_select_db fails every second time. I'm looking at why now.

The following code produces some odd behaviour with respect to sybase connections.
for ($i=0,$i<10,$i++) {
1. $link = sybase_connect("x","x","x");
2. echo "Link ID = $link -- ";
3. sybase_select_db("x");
4. $result = sybase_query("select ...");
5. echo "Result ID = $result";
6. $row = sybase_fetch_row($row);
7. echo "query result = $row[0]";
8. echo "------------- <br>";
}
This code gives me the following output:
Link ID = Resource id#1 -- Result ID = Resource id#2
query result = x
-------------
Link ID = Resource id#1 --
Warning 1 is not a valid Sybase-Link resource in line 3
Warning 1 is not a valid Sybase-Link resource in line 4
Result ID =
Warning Supplied argument is not a valid Sybase result resource in line 6
query result =
--------------
The above pattern repeats itself with the Link ID now Resource id#3 and Result ID = Resource id#4,
etc
Removing Lines 6 and 7 gives :
Link ID = Resource id#1 -- Result ID = Resource id#2
Link ID = Resource id#1 -- Result ID = Resource id#3
Link ID = Resource id#4 -- Result ID = Resource id#5
Link ID = Resource id#4 -- Result ID = Resource id#6
Link ID = Resource id#7 -- Result ID = Resource id#8
Link ID = Resource id#7 -- Result ID = Resource id#9
etc
Adding a sybase_close fixes the problems
Link ID = Resource id#1 -- Result ID = Resource id#2
Link ID = Resource id#3 -- Result ID = Resource id#4
Link ID = Resource id#5 -- Result ID = Resource id#6
PHP modules: --with-apache (1.3.12)
--with-sybase-ct (11.0.0.3)
--enable-trans-sid
PHP.ini : default except for sybase severity errors on 11
Hope this helps
Thanks
