Description:
------------
PHP Version 5.2.1 (form wouldn't let me select this version)

Reassigning a string index to ''
doesn't modify the string's length.

Reproduce code:
---------------
$ php -r '$str = "foo"; $str{0} = ""; var_dump($str);'

Expected result:
----------------
string(2) "oo"

Actual result:
--------------
string(3) "oo"

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

The first character will be a Null-Byte after that operation which is not shown by your terminal/browser/...
