Doing a var_dump() on $ODBCConnect shows that a boolean False is 
returned.

When False is expressed as a string (as in your example), an empty 
string is the result.

This is expected behaviour.

http://www.php.net/manual/en/language.types.string.php#language.types
.string.casting

"A boolean TRUE value is converted to the string "1". Boolean FALSE 
is converted to "" (the empty string). This allows conversion back 
and forth between boolean and string values."
