Description:
------------
The <> operator matches different when passing code directly to CLI mode using the -r parameter vs. a file using the -f parameter.

Test script:
---------------
php.exe -r "error_reporting(0); $a = array('parent' => array('existing' => '0')); var_dump($a['notExisting'] <> "0"); var_dump($a['notExisting'] <> $a['parent']['existing']);"

---
vs.
---

php.exe -f test.php
with test.php has the contents:
<?php error_reporting(0); $a = array('parent' => array('existing' => '0')); var_dump($a['notExisting'] <> "0"); var_dump($a['notExisting'] <> $a['parent']['existing']); ?>

Expected result:
----------------
bool(true)
bool(true)

---
vs.
---

bool(false)
bool(true)

Actual result:
--------------
bool(false)
bool(true)

---
vs.
---

bool(false)
bool(true)

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

in cmd, you should write two quotes(escape) in the quote string:

php.exe -r "var_dump(NULL <> "0");" 

should be:

php.exe -r "var_dump(NULL <> ""0"");"

otherwise, I guess CMD will take it as:
php.exe -r "var_dump(NULL <> 0);"

or:
php.exe -r "var_dump(NULL <> '0');"
