Description:
------------
---
From manual page: http://www.php.net/function.strpos#refsect1-function.strpos-returnvalues
---

If the input to strpos is invalid the function used to return false.  Now it returns null.  Null is not a documented return value for this function.

Test script:
---------------
php -r 'var_export( @strpos( array( "" ), "test",  0 ) );echo "\n";'

Before php 5.3
false

After PHP 5.3
NULL


Expected result:
----------------
false

Actual result:
--------------
NULL

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

not found and invalid argument are differenet.

See note in http://php.net/functions.internal we don't document that for all functions individually.

Please fix the documentation

http://php.net/manual/en/function.strpos.php
