This problem is solved since nearly 5 years with PDO. You can use an 
abstraction like DDDBL (see my signature) if you want to save time while 
using PDO.

[GENERAL] PHP and PostgreSQL boolean data type

2010-02-10 Thread Thom Brown 
Hi,

A long-standing problem we've had with PostgreSQL queries in PHP is
that the returned data for boolean columns is the string 'f' instead
of the native boolean value of false.

An obvious example of this would be for a table with users and their
boolean registered status:

Select user, registered From users;

Then getting a row from the result would reveal: array('user' =
'thomb', registered = 'f');

Another problem is with arrays, where they are difficult to parse as
they also come through as plain strings with no binary alternative.

 Is this a limitation of libpq or a flawed implementation in the php
library?  And if this is just the case for backwards-compatibility, is
there a way to switch it to a more sensible PHP data type?

Thanks

Thom

Using PDO(http://no.php.net/pdo) will at least give you native values 
for true/false. Arrays, I don't know, since I don't use them.

Thanks guys.  I can see that this is specifically a PHP issue then.
It seems like an extreme workaround though.  I'd rather see the PHP
library updated in a way that would somehow not break existing code
which checked for an 'f'.  Not quite sure what the solution would be.

Thanks

Thom
