In PHP 4.3-DEV with Zend2, the constants True and False are undefined, so if you do:

$x=0;
if ($x!=True) {
  echo "It must be True then...";
}

It evaluates the expression as true, and you see no error unless you increase the error reporting level.

This simple script:

<?php
  
var_dump(True);
var_dump(TrUe);
var_dump(False);
var_dump(FaLse);

?>

Outputs:

bool(true)
bool(true)
bool(false)
bool(false)

With latest CVS HEAD of PHP + ZE2..so it's fixed (or was never broken even..you should check for TYPE too by using !== instead of != )

This bug is still open !
When you try the following script with the last windows binaries from http://snaps.php.net/win32/ze2

<?php
  
var_dump(True);
var_dump(TrUe);
var_dump(False);
var_dump(FaLse);

?>

Outputs:

string(4) "True"
string(4) "TrUe"
string(5) "False"
string(5) "FaLse"

This bug is definitely fixed in CVS.
