Description:
------------
This is a problem with === true and !== true whether used with strpos or with array_search and presumably with other functions.

This also fails under PHP 4.3.10 on FreeBSD 4.8-STABLE,
but that is a hosted server and I can't upgrade it to test.

I have done further testing and found that 
checking for === false or !== false is OK:
=== false works when statement is true
=== false works when statement is false
=== true doesn't work when statement is true
=== true works when statement is false
!== true  doesn't work when statement is true
!== true  works when statement is false
!== false works when statement is true
!== false works when statement is false
Pls get in touch if you would like the code to show that. 


Reproduce code:
---------------
<?php

if (strpos("hey","h") === true) print "1. worked \n";
else print "1. didn't work\n";
if (strpos("hey","h") !== false) print "2. worked \n";
else print "2. didn't work\n";
?>


Expected result:
----------------
1. worked
2. worked


Actual result:
--------------
1. didn't work
2. worked

strpos doesn\'t return true on success but the position

I reported this as a documentation issue using the web form found from the manual. The response was to report it as a bug. So I did. Now I will go back and report it again as a documentation issue and submit my own documentation comment.
