Bug Type: PostgreSQL related
Operating System: Ubuntu 7.04
PHP Version: 5.2.6

Description:
------------
I'm using Ubuntu Feisty Fawn 7.04 with Apache with PHP 5.2.4 and
Postgres v.8.2.4.
I have noticed that, when querys are run, logical variables are not
correctly assigned.
E.g. being 'lists' the table defined by the SQL sentence:
CREATE TABLE lists
(
active boolean NOT NULL DEFAULT true,
reference serial NOT NULL,
caducated boolean NOT NULL DEFAULT false,
name character varying(100) NOT NULL,
...
)
and the PHP code
// creation of the SQL sentence
$consulta="SELECT * FROM lists WHERE ((referencie=".$mykey.") AND
(active=true))";
// Execution
$result = pg_query($consulta)
or die('Error in SQL query:'.pg_last_error());
if (pg_num_rows($resultado)>0) { {
$line = pg_fetch_array($result, null, PGSQL_ASSOC);
if ($line["caducated"]==true)
{ ... -code executed if condition=true- }
else
{ ... -code executed if condition=false- }
...
I realized that the 'else' code was executed ALWAYS. It did not matter
if the condition was $line["caducated"]==True, or TRUE, or 1, or False
or FALSE or 0.
I noticed that logical variables are assigned to 't' or 'f' instead of
'true' or 'false' (or numbers) and their type is not correct (the
result of gettype($line["caducated"]) is "string"- , so, the only way to
execute correctly the 'if' sentence is by typing "if
($line["caducated"]=='t')" (or "$line["caducated"]=='f'")
which violates the reference syntax of PHP, that states that to specify
a boolean literal we have to use keywords TRUE or FALSE (both
case-insensitive).
Also, sometimes, asignation of variables inside the if or else blocks
is made in a wrong way.
