From manual page: http://www.php.net/function.odbc-connect#refsect1-
function.odbc-connect-returnvalues
---

"Returns an ODBC connection id or 0 (FALSE) on error."

Out of habit, I usually code with the following sort of conditional construct

if (false !== ($foo = bar()))
{
   echo 'Houston we have a problem';
}
else
{
   echo 'bar() was good';
}

The documentation is not good enough for this function to test equality with 
type equivalence. The function odbc_connect does not actually return FALSE. It 
returns 0 or a connection id.

The documentation should state "Returns an ODBC connection id if successful, or 
returns 0 on error."


Test script:
---------------
<?php

// requires ODBC support
$db = odbc_connect('this','should','fail');
print_r($db);

?>

Expected result:
----------------
According to the documentation, it could spit out FALSE.

Actual result:
--------------
It always spits out 0.
