Description:
------------
I cannot connect with:
$var=odbc_connect('myodbc-test','root','password');
to my MyODBC data source.

Here is the error:
Warning: odbc_connect(): SQL error: [unixODBC][Driver Manager]Can't open lib '/usr/lib/libmyodbc3.so' : unknown error, SQL state IM003 in SQLConnect in /home/httpd/bagr/docs/test.php on line 2

I would appreciate any help. Below is some more info.

isql command work fine:
echo "show tables;
> " | isql myodbc-test root password

I hope it's enough.

Reproduce code:
---------------
$var=odbc_connect('myodbc-test','root','password');

Expected result:
----------------
Should connect without errors :-)

Actual result:
--------------
