New Comment:
Sorry, that code example should have been the following (same result
happens):
<?php
if (($db = mysqli_connect('localhost', 'user', 'password',
'db')) ==
false)
{
echo 'equals false';
}
else
{
echo 'does not equal false';
}
?>

Ok, but then why does this work as expected (when a valid host,
username, password, and db are supplied):
Reproduce code:
---------------
<?php
if (($db = mysqli_connect('localhost', 'user', 'password',
'db')) ===
false)
{
echo 'equals false';
}
else
{
echo 'does not equal false';
}
?>
Expected result:
----------------
does not equal false
Actual result:
--------------
does not equal false

PHP is loosly typed so comparing an object with a boolean will result
in this behavior.
try comparing with === or check the type of the returned object.

Description:
------------
The manual states that simplexml_load_string (and simplexml_load_file)
returns false on any errors. In the following example, I am loading a
valid xml stream, but the simplexml object returned seems to equal
false when it shouldn't.
Reproduce code:
---------------
<?php
$doc = simplexml_load_string('<xml></xml>');
if ($doc == false)
{
echo 'equals false';
}
else
{
echo 'does not equal false';
}
?>
Expected result:
----------------
does not equal false
Actual result:
--------------
equals false
------------------------------------------------------------------------
