Quite a few functions in php do this. If you use the
syntax == or != it is C-style compare. That is, zero
is false and basically the rest is true.

If you use === or !== it evaluates to true if both
the types are equal AND the statement is true.

So, the correct syntax would be

if (false === ($customer_id = $db->getone("..."))) {
error handling.
}

Example from the manual:
// in PHP 4.0b3 and newer:
$pos = strrpos($mystring, "b");
if ($pos === false) { // note: three equal signs
// not found...
}

By doing this, strrpos can return 0 (not an error) or
false (not found). Without === strrpos would have to
return -1 or some other illegal position for not found.
